Prep the aromatics: Finely grate the garlic on a microplane or mince it very finely. Zest the lemon, then cut it in half and juice it.
Stir the base: In a medium bowl, combine the double cream yoghurt and mayonnaise until smooth.
Flavour it: Add the lemon zest, 1 tablespoon lemon juice, grated garlic, and olive oil. Mix until fully combined.
Season: Add 1/2 teaspoon sea salt and a few grinds of black pepper.
Taste and adjust with more lemon juice or a small squeeze of honey if it’s too sharp.
Herbs in: Fold in the chopped herbs. Keep some aside for garnish if you like.
Optional heat: Sprinkle in a pinch of smoked paprika or chilli flakes for a subtle kick.
Rest briefly: Let the sauce sit for 5–10 minutes so the garlic mellows and the flavours meld.
Serve: Transfer to a small bowl. Drizzle with a little olive oil and finish with a dusting of paprika or extra herbs.
