A creamy white garlic sauce to use on anything. I love to use it on fries.
Operating with minimal equipment requires precise heat control. A standard medium saucepan works best for distributing heat evenly across the base fats. Melt two tablespoons of butter alongside two tablespoons of oil over low heat. Fat coats the flour particles, preventing rapid starch swelling that causes lumps. Whisk the all-purpose flour into the melted fats off the heat first. This creates a dense, paste-like consistency known as a roux. Return the pot to low heat before introducing liquids to cook out the raw flour taste.
Pour the milk into the warm roux gradually while whisking constantly. Constant agitation breaks apart starch agglomerates before they can form solid lumps. Incorporate minced garlic, salt, pepper, and parsley during this continuous mixing phase. If the mixture remains too thin, sprinkle in additional flour in half-teaspoon increments to tighten the emulsion. Conversely, thin out an overly thick sauce by streaming in warm milk one tablespoon at a time until the liquid coats the back of a spoon smoothly.
