Pesto

Basil oxidizes on contact with metal (blender blades) and from friction heat. Trick 1: blanch basil in boiling water for 5 seconds then immediately into ice water — chlorophyll is fixed. Trick 2: add a few parsley leaves — they are more color-stable. Trick 3: pour a thin layer of olive oil over the finished pesto in the jar — oil seals it from air. Proper pesto stays green for up to 5 days in the fridge.

Pine nuts are expensive and commonly substituted. Best alternatives: walnuts (more bitter but works), cashews (mild neutral taste, creamy texture — very close), hazelnuts (fatty and sweet — interesting result), sunflower seeds (budget-friendly, slightly different flavor). Any nuts should be lightly toasted in a dry pan first — this releases their aroma.

Authentic Pesto alla Genovese is made only in a marble mortar — basil is ground in circular motions, never chopped. Blender blades heat and tear basil cells — the flavor changes. The recipe uses only Genovese DOP basil (small-leafed, very aromatic), Ligurian olive oil, Parmigiano Reggiano, pecorino, pine nuts, garlic, salt. No lemon, no additives. Jarred pesto is pasteurized with preservatives — fundamentally different taste.

The list is long. Spread on bread or bruschetta. Sauce for pizza instead of tomato. Marinade for chicken or fish before roasting — just coat it. In minestrone soup — add a spoonful at the end. In risotto — stir in at the end of cooking. Dressing for potato salad. With poached eggs. In sandwiches with mozzarella and tomatoes. A spoonful stirred into an omelette.

Yes — pesto freezes excellently. Best method: pour into ice cube trays, freeze into cubes, transfer to a zip bag. Each cube is roughly one pasta serving. Thaw at room temperature or drop directly into hot pasta. The flavor after freezing is practically unchanged — the color may darken slightly. Keeps in the freezer up to 3 months.
