‘Pico de gallo’, meaning ‘rooster’s beak’, is certainly one of the most popular salsas in Mexico. Made up of red onion, tomatoes, serrano chilli, coriander and lime juice, it’s a celebration of all the flavours we love, and refreshes with every bite. I came across a few riffs on this great salsa on my travels – some with orange, some with jicama, some with tomatillo – what I learnt was that the most important element is the uniform size of the salsa and the balance of acid to natural sweetness.
