Delicious, packed with flavor, and easy: thats the name of the game with this elegant recipe, which takes its flavorful cues from mexico. First, youll make a delicious spicy jalapeo mayonnaise. Then, youll crisp up corn tortillas in oil to make the tostada base. (keep an eye on the heat to avoid burning the tortillas. ) all thats left to do is stir together the crab with shallot, celery, and enough lime juice to take remove any raw, oniony-bite bite out of the shallot. Shopping tip: if you are short on time, you can buy pre-toasted tostada shells, though they wont be as tasty as the diy version.
