Kidney has a bold flavor, so a short soak, mushrooms, onions, garlic, and broth help round it out. Keep the pieces small and cook just until tender.

Ingredients

• 1 lb beef kidney, trimmed and cut into bite-size pieces
• Cold salted water or milk for soaking
• 2 Tbsp olive oil or beef tallow
• 1 onion, sliced
• 8 oz mushrooms, sliced
• 2 garlic cloves, minced
• 1/2 cup beef broth
• Sea salt, black pepper, and parsley

Directions

1. Soak kidney 30 to 60 minutes, then drain and pat dry.
2. Cook onion and mushrooms in oil or tallow until browned.
3. Add garlic, then add kidney pieces and sear quickly.
4. Add broth and simmer 5 to 8 minutes, until just tender.
5. Season and finish with parsley.
