Tip 2

Keep weights on during entire cooling and refrigeration process to compress layers into a sliceable terrine.

Tip 3

Allow pave to come to room temperature before final sauteing to ensure even heating throughout.

FAQ

Can I make this without a mandolin?

While possible with a very sharp knife, a mandolin ensures the paper-thin, uniform slices essential for proper layering and even cooking throughout the terrine.

What if my pave falls apart when slicing?

Ensure adequate compression time with weights and that the pave is properly chilled. Cut with a sharp knife in sawing motion rather than pressing down.

How long will this keep in the refrigerator?

The prepared pave will keep for up to 3 days refrigerated. Reheat individual portions in a skillet and oven as directed for best results.
