Fresh green chili, garlic, wild ginger, shallot, lemon grass, salt, kaffir lime, sugar, galangal, coriander seeds, cumin, cardamon, tumeric: That's the ingredient list on the tub of Thai green curry paste in my refrigerator. No artificial ingredients, no additives, no unpronounceables. So, call store-bought curry paste a convenience food, if you must, but this is one convenience food I always have in my pantry. I'm partial to two brands, Mae Ploy and Maesri, sold in nearly identical little plastic tubs in most Asian markets (and online). Both are made with all-natural ingredients, and either will enhance this green curry fish with asparagus and peas. Use any white fish from the market, and if it's not asparagus season, try green beans or zucchini. Just keep it green.
