Ocopa
Arequipa's picanterías put ocopa on the table as a starter, a pale olive sauce spooned thickly over sliced boiled potatoes, and the smell of toasted chillies and huacatay (black mint) is what sets it apart from Lima's huancaína. The chillies are dried ají mirasol, charred in a dry pan, which gives a smoky, raisin-like warmth rather than sharp heat, and toasted peanuts make the sauce nutty and almost velvety. Many cooks thicken it with crackers; this version uses only peanuts and cheese, so it stays gluten free. Serve it at room temperature with yellow potatoes, a black olive and a few lettuce leaves, plus a halved boiled egg for anyone who eats eggs. The mistake people make is toasting the onion and chillies black, which turns the sauce bitter; they should be blistered in spots only. Queso fresco is often made with animal rennet, so look for a vegetarian fresh cheese. Chef's tip: huacatay paste comes in jars from Latin shops; without it, use a small handful of mint plus a few tarragon leaves.
