This simple summer dip combines guacamole with sweet grilled corn and tangy Cotija cheese. The key to great guacamole is to pound the aromatics in a mortar and pestle or molcajete with salt, producing a guacamole with deep flavor from minimal ingredients.

Preparation

  1. Step 1

    Prepare a coal or gas grill so it’s at high heat. Add the corn and cook, turning occasionally, until the kernels are lightly blackened in spots all over, 5 to 15 minutes. When corn is cool enough to handle, hold one ear upright in a large bowl and, using a sharp knife, cut off the kernels. Discard the cob, then repeat with the other ear. Let cool completely before adding to the finished guacamole.

  2. Step 2

    Meanwhile, in a large granite mortar and pestle or molcajete (see Tip), combine the onion, chile, cilantro and salt. Pound into a rough paste, 2 to 4 minutes. Transfer the paste to a large bowl.

  3. Step 3

    Add the flesh of the avocados and the lime juice. Crush the avocados into a chunky dip using the pestle or the back of a large spoon. Once corn kernels are completely cooled, add them and the Cotija to the large bowl, reserving a little of each for garnish. Fold together the guacamole, corn and cheese, and season to taste with more salt and lime juice. Sprinkle with remaining cilantro, Cotija and corn. Serve immediately with tortilla chips. (Try to eat in one sitting. Leftover guacamole stored in the fridge turns brown quickly.)

Tips
  • A granite mortar and pestle or molcajete crushes plant cells more effectively than a knife or a food processor, which, in turn, lends more flavor to the guacamole. If you don’t have a granite mortar and pestle or molcajete, combine the onion, chile, cilantro and salt in a small bowl and let rest for 10 to 15 minutes to draw out moisture. Transfer to a cutting board and chop very finely with a chef’s knife, then, using the side of the knife, smear and crush the ingredients until they form a paste. Transfer to a large bowl and continue as directed in Step 3.
  • To broil, heat the broiler to high and adjust an oven rack to 4 to 6 inches below the broiler element. Place the shucked corn on a rimmed baking sheet and broil, turning occasionally, until kernels are lightly blacked in spots all over, 5 to 15 minutes.

Cooking Notes

Another way to "grill" (or at least brown/char) the corn is to coat the shucked ears very lightly with oil and turn them several times in a hot cast-iron skillet. Cool and scrape as directed. That's the way I do it; in a large enough skillet, I can easily do both ears (or more than two) at once. And please, do not discard the cobs! Save them to make a slightly smoky corn stock.

If it were me, I'd add some finely chopped fresh summer tomato! The combination of the grilled summer corn and summer tomatoes adds complexity. And, please, always use serrano not jalapeño!

Agreed that mortar and pestle is key for extracting flavor (same applies to pesto). Only difference that I do with guac is to add the lime juice with the onions to sort of pickle them and mellow their flavor a bit. Not sure if there is a downside to that. Adding roasted corn and cotija is fantastic.

I think I'll be very lazy and use TJ's delicious frozen roasted corn.

Don't throw away the corn cobs! Toss in the freezer, and use for vegetable stock and soups. You won't believe how much flavor they pack!

If you have left over guacamole, cover with tortilla chips pressed slightly into the surface and put a lid or wrap on the container. When you go to reuse it, you'll have to throw those chips away - they get soggy - but it keeps the air off the guac so it doesn't turn brown.

re: keeping guac green - scrape leftover guac onto plastic wrap and then roll it up like you would a compound butter (to make a log, but a short one to minimize surface area) and twist the ends like a taffy wrapper, eliminating as much air as possible. the only way to keep it green is to keep air away from it. pits will not do anything. citrus does not do anything either. the amount of citrus needed to keep it from browning would make it inedible. (1/2)

Guacamole is similar to gazpacho in that both go back many, many centuries and come in many forms, colors and mixtures. Rather than debate whose version of guacamole is most "authentic," open your hearts and minds to trying something a little--or maybe even a lot--different. As for choosing avocados, we buy Haas avocados only when they are hard as a rock, leave them in a bowl on the table for a day or two and eat them when they first show signs of slight give or softness.

I agree! Microwaving the corn ears while still in the husks is so easy. 3 to 4 minutes, depending on the size. Then cut off about 1/2 inch off the bottom and squeeze the corn ear out while grasping the silken end with a kitchen towel. Pops right out with nary a thread of silk on it.

From AvoSeedo: "Putting golf balls in your guacamole would be just as effective as putting pits in there to keep it from turning brown" because it's keeping oxygen from the guac.

highly recommend steaming corn first and then high temp char. you will retain more flavor and remove part of the starchiness.

Made this for Saturday night appetizers and it was a delight. I used my Japanese suribachi for the first time to make guacamole and I will always use it in the future. The result was much better than just mixing everything together and it seems to work as well as a molcojete. The grilled corn really sweetens the dish and I used Parmesan reggiano, which makes everything better. I also used Fresno chilies, my favorites, perfect balance of heat and sweetness

This sounds amazing and perfect for end-of summer. I make something similar but as more of a salad, with the avocados chopped vs mashed, and sometimes I'll throw in some diced cucumber for additional crunch.

This dip was a huge hit at a summer party. I charred the corn in an iron skillet as suggested and it looked beautiful. I added some halved cherry tomatoes since we have a bumper crop and substituted fresh parley and oregano from the garden since I had forgotten to buy cilantro. I will definitely be making this again and will remember the cilantro.

What's all the concern about keeping the leftovers green? Who has leftovers? This was worth all the work and thank you for the tips for those of us who have neither yards to grill in nor kitchen space to store a molcajete.

Absolutely delicious! I introduced garlic into the mortar-and-pestle blend and added diced tomatoes alongside my cast-iron grilled corn. Impeccably done. Three serrano peppers to this quantity gives a rather satisfying level of heat that gets tamped down nicely by the rest of the guac.

To make it last longer, and avoid the browning of avocado issue, we divide the onion-cilantro paste into two and mix one large/jumbo avocado with half the paste on night one and the second on night two

Delicious! And substantial. I used half a bag of the frozen roasted corn from Trader Joe’s because corn is out of season right now and it turned out so well. I also added a few dashes of green Cholula hot sauce, a bit of salt, and anotber squeeze of lime at the end to season, all of which amped up the flavor. Will make again!

This was good, but it needed a little spicing up. I seeded the serrano pepper. I think the next time I make it (and I will) I'll leave the seeds in.

It's hatch chili time out west. I roasted one and put it in the guacamole together with one cob of grilled corn. Used lemon instead of lime. All good.

If you want to prevent your finished guacamole turning brown, press it firmly into a clear glass storage dish, making sure to get all the air bubbles out, then cover with plastic wrap, pressing the plastic wrap onto the guacamole, not letting any air bubbles remain under the wrap. Put a lid on the whole dish and pop into the fridge.

I'm allergic to limes so always use fresh lemon juice in my guac. It adds a slightly different zip, I suppose but it's delicious. Also, I find that a finely chopped up tomato is perfect for a great guacamole. I'm wondering if I could sub the corn for the tomato. Hmmmm. I may try this - or maybe both at once!

Delicious but will add garlic next time.

Used a few substitutions because we didn't have all the ingredients. Canned organic corn grilled in teaspoon of olive oil and Costco goat cheese (always in the frig instead of cojita. Delicious!

For the last 50+ years, people from San Antonio TX have made guacamole by mashing ripe avocado with Pace's Picante Sauce (Mild, Medium, or whatever) to taste. Squirt a bit of lemon in it if you like ... or not ... Fast and fabulous.

Don't pre-cook the corn!!! The grilling is enough to draw out the sugars and keep it crunchy in the dip. Toss in whatever diced veg you love or some black means. Leftovers??? LOL!!

For the corn I was able to roast it over the stove burner, with a strong exhaust fan—like you would for peppers. Also could not find Cotija but Feta was recommended as a sub so I used that and it was great.

We loved it, the fresh corn adds a nice dimension. Had leftover tomatillo salsa that I made, the combination is wonderful. The cotija was pretty salty, so taste before you add the salt. Will make again when corn season rolls around.

I love guacamole, and have a favorite recipe, involving charred tomatillos. I also love corn, and cheese, so when I saw this, my mouth watered. What I learned is that, while I also love pasta and raspberries, they don't go well together. I made this exactly as laid out, going so far as making a second trip to the market to get fresh corn, when the avocados didn't ripen soon enough. Overall, this is just a weird combination of ingredients. It's not terrible; it's just not good.

I made this for guests 8 months ago. Talking with them today they brought up the “best guacamole ever!” We all agreed. True, tastes differ. But it’s always tempting to figure out what went wrong. The general key is to taste, adjust and taste again. This recipe calls, in step 2, for a pesto to be made, suggesting 2-4 minutes to do it. That’s not enough time if using granite. Don’t cut corners: the onion, chile, cilantro and salt need to be nearly emulsified. And the Chile must be hot.

If I keep a pit to the avocado and place it in the guacamole it keeps it from turning brown.
