Helado picante

Fegato piccante is a traditional dish originating from Tuscany. It's made with a combination of calf's liver, olive oil, butter, wine vinegar, salt, pepper, and sage. The olive oil and butter are heated in a pan, and the liver is then cooked in the combination for a few minutes. It is then seasoned with salt and pepper and cooked with vinegar and sage until the mixture comes to the boiling point. The calf's liver in wine vinegar is served immediately out of the pan, while still hot.
