Bistec
Bistek , also known as bistek tagalog or karne frita, is a Filipino dish consisting of thinly-sliced beefsteak braised in soy sauce, calamansi juice, garlic, ground black pepper, and onions cut into rings. It is a common staple in the Tagalog and Western Visayan regions of the Philippines. It is eaten over white rice. Bistek tagalog is made of strips of beef sirloin or tenderloin, usually flattened with a meat tenderizing tool, it is marinated then braised in soy sauce, calamansi juice (or some other citrus fruit like lime or lemon), smashed whole garlic cloves, ground black pepper, bay leaves, caramelized red onion rings, and (optionally) muscovado or brown sugar. In some recipes, fresh white onion rings are used instead to preserve its crunchiness.
