For best flavor, use al dente pasta and let the salad rest in the fridge so the dressing absorbs into the noodles without becoming mushy; if making ahead by several hours, reserve some dressing to stir in right before serving because pasta continues to soak it up, and add avocado at the last minute to prevent browning. Charring the corn well is key to developing the classic street-corn flavor—if you have access to a grill, char whole ears and cut off the kernels after, or use a very hot dry skillet for frozen corn. Adjust heat with more or less jalapeño and chili powder, and if cotija is unavailable, feta is a good substitute, while Greek yogurt can stand in for some or all of the sour cream for a lighter version.
