Ingredients for the No-Cook Tuna Mousse
- 7 oz tuna in oil (drained weight)
- 1 cup cow's milk ricotta (or robiola or other spreadable cheese)
- 2 pinches black pepper
- 10 sprigs black olives (or green)
Tools
- 1 Immersion Blender
Preparation
Preparing the tuna mousse is really easy and quick. First, drain the tuna in a fine-mesh strainer for at least 30 minutes.
Then, dry the olives, place them in the immersion blender cup (or a cutter) with the tuna and blend well.
Transfer the tuna to a small bowl and add the ricotta that you have previously drained from its whey.
Mix, season with freshly ground black pepper, and let the no-cook mousse rest in the fridge for at least 30 minutes before using it.
If you want to add capers and parsley, chop them in the blender with the tuna and olives.
You can replace the ricotta with robiola (thicker) or mascarpone (for extra indulgence).
Storage
The no-cook mousse can be stored in the refrigerator for 3 or 4 days, well-sealed in an airtight container.
No-Cook Tuna Mousse Variants
Lemon and Ginger Flavored Mousse:
Add: The grated zest of half an untreated lemon and a pinch (less than half a teaspoon) of freshly grated ginger.
Result: An unexpected freshness that “cuts” the richness.
Intense Mousse with Capers and Anchovies:
Add: 1-2 teaspoons of desalted capers (or in salt) and 1-2 anchovy fillets in oil (very few, for flavor but not to dominate).
Result: Intense flavor and savoriness, perfect for those who love strong tastes.
Herb Scented Mousse:
Add: A generous amount of chopped chives and a few leaves of basil or mint (the latter is bold but very fresh).
Result: Bright color and an herbal aroma that pairs excellently with fish.
Spicy and Crunchy Mousse:
Add: A pinch of chili powder or paste (like Harissa if you love exotic) and, only at the end, manually add coarsely chopped pistachios.
Result: A contrast of spiciness and crunchiness.
Colorful Mousse with Sun-Dried Tomatoes:
Add: 3-4 sun-dried tomatoes in oil, well-drained, and 1/2 clove of garlic (optional).
Result: A sweet and sour touch and a nice pink color.
