Overview: Roscoe Hall presents a Dirty Martini Granita recipe at Food & Wine Online, published November 12, 2026. The preparation serves as a briny alternative to traditional mignonette for oysters on the half shell.
The Full Story
Olive brine echoes the oysters’ salinity, while gin’s botanicals and vermouth’s herbal notes add complexity. Lemon juice supplies just enough acidity to balance the salty topping without masking the shellfish’s sweetness. Roscoe Hall is more than just a chef — he’s a culinary force with a gift for making cooking both approachable and fun. Roscoe trained under Alice Waters at the iconic Chez Panisse, worked alongside the legendary David Chang at Momofuku, and was the executive chef at Rodney Scott’s BBQ.
Production & Profile
The recipe yields 8 servings using 1/4 cup gin, 2 tablespoons dry vermouth, 1/4 cup Castelvetrano olive brine, 1/2 cup water, and lemon juice. Whisk together all ingredients in a 9- x 13-inch baking pan. Freeze, uncovered, for 4 hours, scraping with a fork every 40 minutes to create small ice crystals. If mixture is slushy, add another 1⁄4 cup water and freeze, uncovered, for 40 minutes. Choose a London dry gin with a pronounced juniper character to complement the olive brine and oysters. Avoid sweetened or strongly flavored gins, which can distract from the shellfish.
What This Means
Dirty Martinis and a platter of oysters are a natural pair, and this granita brings the two together in one briny bite. It’s a playful change from mignonette, especially for anyone who favors a Dirty Martini alongside a dozen oysters on the half shell.
Consumer Takeaway
This recipe was developed at its original yield. Spoon a little onto each oyster just before serving, while the ice crystals are still distinct. Cook this recipe and more in the MyRecipes app.
