Onions, garnishes, and prepping the table
Ok so everything we've built so far—salsas, corn, the meat sequence—all of it lands on a table at some point. This lesson is about the stuff that makes the table actually work: the diced onion, the little bowls, the setup that means you're not running back to the kitchen every four minutes while people are eating.
Let's do onions first since that's the one everybody skips or does wrong.
Diced onion, done right
White onion, quarter-inch dice, give or take. Not minced into mush, not big chunks you have to bite through. You want it small enough that a spoonful gives you onion in every bite of taco without it taking over.
Here's the thing about raw onion for tacos: it's sharper than you think it needs to be, and a lot of people find that harsh straight out of the bag. Easy fix. Dice it, then let it sit in a little cold water for 10 minutes while you're doing something else. Drain it, pat it dry-ish. Takes the raw edge off without cooking it. Ximena's the one who taught me that one actually, not the mission dad. She just does it out of habit.
If you want a little color and a little sweetness, char a few slices of onion right alongside your meat when you're searing it — same logic as the corn, same logic as the chiles. Black spots aren't a mistake. That's the technique doing its job. Chop those charred pieces in with the raw diced stuff and you get both textures in the same bowl.
Radish, cabbage, the extras
Radish sliced thin, on a mandoline if you've got one, or just careful knife work if you don't — thin blades and rushing don't mix, so slow down on this one. Shredded cabbage if you're doing more of a Baja-style thing on the side. These aren't required. I put them out because some people want the crunch and some people don't, and it costs me almost nothing to have both options sitting there.
Setting up the table like a job site
This is the landscaper part of my brain taking over the kitchen, and I dont apologize for it. You lay out your station left to right in the order people are going to build their plate: tortillas warm and covered, meat, onion, cilantro (portioned like we talked about, for your Mckenzies out there), salsas, cheese and cream for the corn if that's still out, lime wedges at the very end of the line.
Left to right, in build order. Nobody has to ask what comes next, they just follow the table.
And every single component needs its own spoon. I know that sounds obvious but I've watched people try to serve four salsas with two spoons and it turns into a whole thing. Buy the cheap plastic ones if you have to, doesn't matter, just have enough.
The freezer confession
I want to tell you about a mistake because I think it's actually useful here, not just embarrassing.
A while back I got ambitious and made this huge batch of al pastor marinade thinking I'd meal-prep myself a month of tacos. Froze most of it, real proud of myself, real efficient. Found it in the deep freeze eight months later. Freezer burned, totally shot. Had to throw the whole thing out.
The planning guy in me wrote that check. The follow-through guy never cashed it. That's basically my whole personality in one Tupperware.
I bring it up here because prepping the table has the same trap. It's easy to over-plan — five salsas, six garnishes, a whole cheese board situation — and then run out of steam before the actual meal happens. My rule now: pick what you'll actually finish and finish it. Three good garnishes on the table beats six half-thought-out ones still sitting in bowls in the fridge.
A word on timing
Everything on this table should be prepped before anybody's hungry and definitely before the meat comes off the heat. Onion diced and soaked, radish sliced, cilantro portioned, limes cut into wedges — all of it done and sitting covered on the counter while the meat's still cooking. Prep everything before the flame comes on. I say that every lesson because I need to hear it as much as you do. I'm bad at this. I will absolutely still be dicing onion while pork's resting if I don't force myself into the sequence ahead of time.
One real caution here: if you're slicing radish or onion thin and fast because you're behind schedule, that's exactly when people nick a finger. Slow down, especially on the mandoline. No shame in going slower than you planned.
Before next time
Grab your onions and do a test batch of the water-soak trick before class, see if you notice the difference in sharpness. Not required, just worth feeling for yourself once.
