Ingredients
Note: Dried ancho, guajillo and arbol chillies are available from specialty food shops. If unavailable, substitute long dried chillies.
Method
Place chillies in a small bowl and cover with 300ml boiling water; soak for 15 minutes or until softened.
For birria sauce, heat a lightly greased barbecue or char-grill pan to high. Grill tomatoes, onion and garlic, turning frequently for about 12 minutes, or until slightly charred. Transfer to a bowl and leave for 10 minutes, or until cool enough to handle. Peel tomato and transfer to a blender with onion, garlic, chillies with soaking water, vinegar, sugar, and spices; blend until smooth and set aside.
Heat oil in a large heavy-based saucepan with a lid over high heat. Season beef and sear in batches, turning frequently until browned all over. Pour in birria sauce, stock and bay leaves. Bring to a simmer, then reduce heat to very low and cover with a lid; cook for 2-2½ hours or until meat is very tender.
Meanwhile, for Charred Pineapple Salsa, cut pineapple in half lengthways, then quarters and remove core. Cook pineapple on barbecue or char-grill pan, turning frequently, until charred all over. Transfer to a board and cut into rough 1cm pieces. Transfer to a bowl, add remaining ingredients and toss to combine; refrigerate until ready to serve.
Remove meat from pan and continue to simmer birria sauce uncovered for about 15 minutes or until sauce has reduced and thickened. Meanwhile, return beef to hot char-grill pan and grill for 1-2 minutes, or until lightly charred. Transfer beef to a serving dish, pour over birria sauce and use two forks to shred.
Serve beef with birria sauce, Charred Pineapple Salsa and warmed tortillas with extra lime cheeks on the side.
