Sriracha Butter Emulsion
A glossy chilli-butter sauce with mellow confit garlic and bright layers of fresh and pickled lemon.
Behind the plate
Sriracha butter turns the neutral master emulsion into a sauce with immediate colour, warmth and acidity. It is fast enough to finish during service and bold enough to transform a simple roasted vegetable or piece of grilled chicken.
The range of sriracha allows the cook to choose the heat level. Start at 20 g for a balanced finish, then build towards 40 g when the dish needs a stronger chilli presence.
Why this recipe works
Confit garlic rounds the chilli heat while fresh lemon brings clean acidity and pickled lemon adds a deeper fermented note. Adding the flavourings to an already stable butter emulsion keeps the finished sauce silky rather than greasy.
The recipe
Ingredients
- Master butter emulsion, as needed
- 15 g confit garlic
- 20–40 g sriracha, depending on the heat required
- Lemon juice, to taste
- Pickled lemon juice, to taste
- Fine salt, to taste
Method
- Prepare the Master Butter Emulsion first and place the amount required for service in a clean saucepan.
- Warm the emulsion very gently without allowing it to simmer or boil.
- Whisk in the confit garlic, 20 g sriracha and a small amount of both lemon juices.
- Whisk firmly or blend briefly with a hand blender until smooth, glossy and evenly coloured.
- Taste, then add more sriracha for heat and adjust the lemon, pickled lemon juice and salt. Serve immediately or hold over very gentle heat.
Chef’s notes
- Begin with 20 g sriracha; it is easier to add heat than to dilute it.
- Do not boil the sauce after adding the chilli because excess heat can split the emulsion and dull its fresh colour.
- Balance the two lemon juices gradually: fresh lemon lifts the sauce while pickled lemon gives it depth.
- If the sauce thickens while holding, whisk in a teaspoon of warm water rather than adding more fat.
At the table
Serve with charred cabbage, roasted cauliflower, sweetcorn, grilled prawns or roast chicken. Finish the plate with a few drops of the sauce rather than hiding the main ingredient beneath it.
