Potted shrimp butter is a traditional British seafood spread made by gently warming small brown shrimp with butter, mace, nutmeg, and a little cayenne, then chilling the mixture until firm. Serve it cold with toast or crackers; its rich, fragrant butter and tender shrimp make a simple but special starter.
Ingredients
- 1 cup (150 g) cooked, peeled brown shrimp, thawed if frozen and patted dry
- 12 tablespoons (170 g) unsalted butter, divided
- 1 tablespoon (15 ml) fresh lemon juice
- ¼ teaspoon ground mace
- ⅛ teaspoon freshly grated nutmeg
- ⅛ teaspoon cayenne pepper, or to taste
- ¼ teaspoon fine salt, or to taste
- ⅛ teaspoon freshly ground black pepper
- 2 tablespoons (30 g) unsalted butter, extra, for the sealing layer
- To serve: 6 slices (about 180 g) toasted bread or 12 crackers, optional
Instructions
- Prepare the shrimp. If using frozen cooked shrimp, thaw them in the refrigerator according to the package directions. Drain well and pat dry so excess water does not make the butter mixture loose. Pick out any shell fragments. Leave the shrimp whole if they are small; roughly chop larger ones.
- Melt the butter gently. Put 12 tablespoons (170 g) butter in a small saucepan over low heat. Once melted, stir in the mace, nutmeg, cayenne, salt, and black pepper. Warm for about 1 minute, just until fragrant; do not let the butter brown or sizzle aggressively.
- Warm the shrimp. Stir in the shrimp and lemon juice. Cook gently for 2 to 3 minutes, stirring carefully, until the shrimp are hot throughout. These are already-cooked shrimp, so the aim is to warm them without making them tough. Transfer the mixture to a shallow bowl and let it cool for about 15 minutes, until no longer steaming.
- Pack into dishes. Spoon the shrimp and spiced butter into six small ramekins or one shallow serving dish. Press lightly to remove large air pockets, but do not mash the shrimp into a paste. Smooth the surface.
- Chill until firm. Cover the dishes and refrigerate for 1 hour. Keep them refrigerated while preparing the butter seal.
- Seal and finish chilling. Melt the remaining 2 tablespoons (30 g) butter in a small pan over low heat. Let it stand briefly so any milky solids settle, then carefully spoon or pour the clear melted butter over the chilled shrimp, leaving the solids behind if practical. Return the dishes to the refrigerator, uncovered until the top firms, about 30 minutes, then cover. Chill for at least another 30 minutes before serving. The full chilling time is 2 hours.
Tips
- Choose the right shrimp. Small brown shrimp give the traditional delicate texture. If they are unavailable, use small cooked, peeled shrimp or chopped cooked prawns; larger pieces make a chunkier spread. Check package labels and use fully cooked seafood.
- Keep the heat low. Butter can separate or brown if overheated, and cooked shrimp become rubbery when simmered for too long. Warm only until hot, then remove the pan from the heat.
- Adjust the spices carefully. Mace is a classic seasoning, but it can be difficult to find. A small pinch of extra nutmeg is a practical substitute, though the flavor will be slightly less floral. Add cayenne a pinch at a time.
- Dry shrimp thoroughly. Water clinging to thawed shrimp can dilute the butter and prevent a neat, firm set. Pat them well with paper towels before cooking.
Serving Suggestions
Serve potted shrimp butter cold, straight from the refrigerator, with warm toast, thin slices of toasted sourdough, crisp water biscuits, or plain crackers. A squeeze of lemon at the table brightens the rich butter. For a starter, offer small portions with cucumber slices, radishes, or a lightly dressed green salad. Let the dish stand at room temperature for about 10 minutes before serving so the butter is spreadable, but do not leave seafood out for more than 2 hours total.
Variations
For a stronger spice profile, add a pinch of ground white pepper or a little extra mace. A small amount of finely grated lemon zest can make the spread fresher and more citrusy. To make a smoother version, pulse the warmed shrimp and butter briefly in a food processor; stop while some texture remains. For a less rich spread, replace up to 2 tablespoons (28 g) of the butter with 2 tablespoons (30 g) of crème fraîche after the mixture has cooled slightly. This variation is softer and will not keep as long or form as firm a seal, so serve it promptly and refrigerate it carefully.
Storage and Reheating
Cover and refrigerate the potted shrimp butter within 2 hours of preparation, or within 1 hour if the room temperature is above 90°F (32°C). Keep it at 40°F (4°C) or colder and use within 2 days for best quality. Although many cooked leftovers keep 3 to 4 days, this seafood spread is best eaten sooner; discard it if it has been left out beyond the safe time or shows an unusual odor or appearance. Do not store it at room temperature or treat the butter seal as a preserving method. Freezing is not recommended because thawing can make the butter separate and the shrimp watery. This dish is intended to be served cold, so it does not need reheating. If you choose to reheat leftovers, heat them to 165°F (74°C) and serve immediately; the texture will be less spreadable.
Frequently Asked Questions
Can I make potted shrimp butter ahead?
Yes. Prepare it up to 1 day ahead, cover, and keep it refrigerated at 40°F (4°C) or colder. Its flavor and texture are best within 2 days. Keep it chilled until shortly before serving.
Can I use frozen shrimp?
Yes, provided they are cooked, peeled shrimp. Thaw them in the refrigerator, drain, and pat dry before using. Do not use raw shrimp in this recipe without cooking them first; raw fish and shellfish should reach the USDA FSIS safe minimum internal temperature of 145°F (63°C), checked with a food thermometer.
Why is my potted shrimp butter runny?
It may not have chilled long enough, or the shrimp may have carried excess water into the mixture. Refrigerate it until fully firm and make sure the shrimp are thoroughly drained and patted dry next time. The sealing layer is not a substitute for proper chilling.
Do I have to use the butter seal?
No. The extra butter layer is traditional and gives the surface a smooth finish, but the spread can be served without it. Cover the dish closely and refrigerate it; without the seal, the surface may dry or discolor sooner.
What does “potted” mean here?
In this dish, “potted” refers to seafood packed into a small dish with seasoned butter and chilled. It does not mean shelf-stable or canned. Keep potted shrimp butter refrigerated and do not store it in a cupboard.
Can I serve it warm?
It is usually served cold or slightly softened so it spreads easily. Warm serving melts the butter and changes the texture. If reheating leftovers, heat to 165°F (74°C) and serve at once rather than holding them warm.
