Red pesto

About red pesto
Pesto alla siciliana, sometimes called simply pesto rosso (red pesto) is a sauce from Sicily similar to Genovese pesto but with the addition of tomato, almonds instead of pine nuts and much less basil. Pesto alla calabrese is a sauce from Calabria consisting of (grilled) bell peppers, black pepper and more; these ingredients give it a distinctively spicy taste. Pesto alla genovese is made with Genovese basil, salt, garlic, Ligurian extra virgin olive oil (Taggiasco), European pine nuts (often toasted) and a grated hard cheese like Parmigiano Reggiano (but which may be Grana Padano, Pecorino Sardo or Pecorino Romano).
