Frequently Asked Questions

Why must flank steak be sliced against the grain?

Flank steak has long, tough muscle fibers running lengthwise. Cutting against perpendicular to these fibers shortens them, making each bite tender.

What is the difference between flank and skirt steak?

Both are lean and flavorful. Flank is wider, thicker, and from the belly. Skirt is thinner, longer, and from the diaphragm with more fat marbling.

How do you keep flank steak from being tough?

Do not overcook - aim for medium-rare to medium max. Slice thin against the grain. Consider marinating with acidic ingredients to tenderize.
