The secret to making amazing Thai curries is to use plenty of aromatics (like onion, ginger and garlic), full-fat coconut milk for richness (you won’t regret it!), and just a little bit of rice vinegar and sugar, which add loads of complexity. Readily available store-bought Thai red curry paste adds characteristic Thai flavor and, bonus, it’s vegetarian, too. You can make your own if you’re so inclined, though.
