Cœur de Veau Sauté (Sautéed Calf's Heart)

Ingredients

• calf's heart
• butter
• a sauce

Instructions

1. Cut the calf's heart lengthwise into very thin escalopes.
2. Season them and sauté them briskly in butter.
3. Add the escalopes to a sauce, or to any sauced garnish, and do not let them boil in it — boiling hardens the heart at once.
