When your sauce is ready, you should see tiny pieces of chilli and minced garlic floating around. These little bits are the life of the sauce.
Paprika is used in a variety of different cuisines but it’s adored by Hungarians. You won’t find a goulash without it. In Spain and Mexico it’s used to flavour chorizo and paella. And in Portugal and Turkey for stews and soups.
