At the end of this course you will be able to:
Blend leche de tigre from grouper trimmings, celery, onion, ají limo and lime juice, then strain it.
Fry the croaker on the skin side only, set it on the sauce and bake it briefly, then finish it in the pan.
Dissolve sugar in soy sauce, stir in chopped ginger, garlic, ají limo and black vinegar, then pour sesame oil on top without mixing.
Brine swordfish in 10% salt for six hours, then smoke it over pecan wood.
About this class
This online Peruvian cooking class is built on two bases. Lourdes water, a fumet of croaker bones with baby clams, sage and parsley, carries the sauces, and leche de tigre, Peru’s citrus marinade, cures the fish.
Lourdes water goes into a croaker fillet with a parsley and confit garlic sauce, and grouper is cured two ways, as ceviche and as tiradito with ají amarillo. The last two lessons borrow from other cuisines: tuna with a Sichuan yuxiang sauce, and smoked swordfish sliced like pastrami for a twist on the Reuben.
