Lobster White Chocolate Soup with Striped Bass

Heat the stock until it barely bubbles. Pull it off immediately. White chocolate and egg yolk go in next — but not into boiling broth. That’s how this breaks.
Why You’ll Love This Lobster White Chocolate Soup
Seafood soup that tastes like a restaurant made it. Takes 37 minutes total — 25 prep, 12 cooking. Creamy without cream. The white chocolate doesn’t make it sweet. It just softens everything and makes the lobster taste more like itself. Served in coffee cups because it’s that elegant. Leftovers taste different the next day. Better, maybe. Bass keeps the soup from being one-note. It’s there but not in the way.
What You Need for This Creamy Lobster Soup Without Cream
Fish stock. Real stuff. Not bouillon. 525 milliliters. White chocolate — finely chopped. 30 grams. Not a lot. One egg yolk. One tablespoon mascarpone mixed together. Striped bass or Chilean sea bass, diced. 150 grams. Cooked lobster about 600 grams — meat shredded, claws saved whole. One scallion, thin sliced. Salt. White pepper. That’s it.
How to Make Lobster and Striped Bass Soup
Get the stock heating in a saucepan. You want small bubbles appearing on the surface — that moment right there. Not a rolling boil. The second it starts to actually boil, pull it off the heat. Boiling reduces it too much and makes it bitter. Stop before you think you should.
Whisk the egg yolk with mascarpone in a small bowl until it’s combined. Just mix. Grab the white chocolate — it needs to go into the hot stock gradually while you stir constantly. Not all at once. The chocolate dissolves into the stock. Then the yolk mixture goes in slowly. Stir hard the whole time. This is what keeps it from breaking. The stirring matters more than you think.
How to Get the Texture Right in Seafood Soup
Put the mixture back on very low heat. Add the diced bass. Add the shredded lobster meat. Stir it but don’t let it boil. The fish is done when it turns opaque and flakes easy. Takes about 4 to 5 minutes. Too much heat and it gets rubbery. Low heat means it stays tender. Season now. Salt. A pinch of white pepper. Taste it. The white chocolate softens the flavor — the fish and lobster should still be the main thing. Don’t oversalt. Adjust sparingly.
Lobster White Chocolate Soup Tips and Common Mistakes
Halve the lobster claws lengthwise before serving. They go on top. Half a claw per bowl. It looks expensive. Serve it hot in medium-sized coffee cups or small bowls. Not soup bowls. Coffee cups make it feel intentional. The scallion goes on just before serving — it cuts the richness with something fresh. Try it without first though. Sometimes you don’t need it.
Don’t skip the fish stock. Bouillon tastes like nothing. Don’t boil the broth. It breaks. Don’t stir the egg yolk in fast. Slow and constant. White chocolate chunks take a minute to dissolve but they will. The bass and lobster both need to go in at the same time. The bass seasons the soup while it cooks. Bass does something to the flavor that makes the lobster better. Not sure why exactly. Just does.

Lobster White Chocolate Soup with Striped Bass
- 525 ml (2 1/4 cups) fish stock or fumet
- 30 g (1 1/16 oz) white chocolate, finely chopped
- 1 egg yolk plus 1 tbsp mascarpone
- 150 g (5 1/4 oz) striped bass or Chilean sea bass, diced
- 1 cooked lobster about 600 g (1 1/3 lb), meat shredded; reserve whole claws
- 1 scallion, thinly sliced
- Salt and white pepper to taste
- 1 Heat fish stock in saucepan until it bubbles gently, not a rolling boil. Remove from heat immediately once small bubbles appear on the surface. This stops over reduction and bitterness.
- 2 Whisk egg yolk with mascarpone in a small bowl until combined. Add chopped white chocolate to hot stock gradually, stirring constantly. Incorporate yolk mixture slowly, keep stirring vigorously; prevents curdling and ensures silky texture.
- 3 Return mixture to very low heat. Add diced bass and shredded lobster meat. Stir continuously but do not let boil. Fish is cooked when flesh turns opaque and flakes gently, about 4 to 5 minutes. Too much heat makes fish rubbery.
- 4 Season with salt and a pinch of white pepper. Taste for balance; white chocolate softens flavor but fish and lobster should remain star. Adjust seasoning sparingly.
- 5 Halve lobster claws lengthwise for an elegant garnish. Serve soup hot in medium-sized coffee cups or small bowls, placing half claw on top for drama and texture.
- 6 Optional: sprinkle sliced scallion just before serving to cut richness with freshness.
Frequently Asked Questions About Lobster White Chocolate Soup
Can I use a different fish instead of striped bass? Sea bass works. Halibut works. Cod probably works too. Avoid anything with a strong flavor. The bass is there to be quiet. It seasons the broth more than it announces itself.
What if I don’t have mascarpone? Heavy cream works. Half the amount. The mascarpone is just there to help bind the egg yolk. It doesn’t need to be mascarpone specifically.
Can I make this without white chocolate? Not really. You could make a straight seafood soup with the bass and lobster. But the white chocolate does something to the mouthfeel. It rounds it. Without it, it tastes like it’s missing something.
How do I know when the stock is ready to come off the heat? Small bubbles. Tiny ones. Appearing at the edges and bottom. Not boiling. The moment it actually boils, pull it. You’ll see the difference once you watch for it.
Does this keep overnight? Yes. Refrigerate it. Reheat gently over low heat. The white chocolate and egg yolk — they’re already cooked, so it’s fine. Just don’t let it boil when you reheat. Same rule.
Why egg yolk and mascarpone instead of cream? Lighter. Silkier without the heaviness. Cream would work but it would taste like cream soup. This tastes like lobster and bass soup that happens to be creamy.
