Craving a potato gratin that truly warms you up without requiring three pots and a half-day? This Dublin-style version keeps the generous spirit of the dish, but replaces the beer with a flavorful broth—simpler to handle and rounder on the palate. Cheddar does the heavy lifting: it browns, it melts, it flavors.
Ingredients :
- Potatoes — They form the structure of the gratin and release just enough starch to bind the sauce. Choose waxy or all-purpose potatoes like Monalisa, Agata, or Charlotte if you want slices that stay well-defined.
- Flavorful vegetable broth — It replaces the deep note of beer without adding alcohol. Use a low-sodium broth if your cheddar is strong, or add a teaspoon of soy sauce for a browner, rounder flavor.
- Milk — It tenderizes the potatoes during pre-cooking and provides a gentle base for the sauce. Whole milk is preferable here, but semi-skimmed works if the cream is generous.
- Heavy cream — It rounds out the reduced broth and gives that velvety texture that coats the slices. Avoid light cream; it can make the sauce more watery and less shiny.
