Continental Mushroom Caviar

Mushroom caviar is a European appetizer that looks and spreads like pate but is made entirely from finely chopped mushrooms. Sauteed with onion in olive oil until just barely soft, then finished with lemon juice, sour cream, and chives, the result is earthy, tangy, and rich all at once.

The key is chopping the mushrooms fine but not pureeing them. You want a spreadable texture with visible bits, not a smooth paste. Cook them just until they release their moisture and soften slightly. Overcooked mushrooms lose their bite and turn into a gray mush.

Chill it well before serving. Cold mushroom caviar firms up and the flavors concentrate as it sits. Spread on crackers or serve alongside thin tomato slices.

Kitchen Tips

• Cook the onion until soft and limp before adding the mushrooms. Raw onion in the finished dish would taste harsh.
• Don’t overcook the mushrooms. They should be just barely soft, not collapsed. They continue to soften as the mixture chills.
• A squeeze of lemon juice brightens everything and prevents the mushrooms from turning dark.
• Make this a few hours ahead. It tastes better after chilling than fresh off the stove.

Variations

• Use a mix of cremini and shiitake mushrooms for a deeper, more complex flavor.
• Add a teaspoon of truffle oil after cooking for a luxurious, earthy upgrade.
• Stir in a tablespoon of capers for a briny pop that nods to actual caviar.
