Lime Leaf Oil Recipe

Blanch and infuse

Rinse the kaffir lime leaves. Stack and roll them, then thinly slice into a chiffonade. In a small saucepan, bring the 2 tbs neutral oil to a gentle shimmer (do not smoke). Add half the chiffonade and quickly blanch for 10–15 seconds to release aroma, then remove with a slotted spoon and reserve. Reduce heat to very low, add the remaining chiffonade and the remaining 1 cup neutral oil. Warm on the lowest heat (barely below simmer) for 20 minutes to gently infuse the oil. Do not allow the oil to fry or boil—keep it at a scenting temperature so the leaves impart bright citrus aroma without bitterness.

Cool, strain, and season

Remove from heat and let cool to warm. Strain oil through a fine mesh sieve lined with cheesecloth into a clean jar. Press gently on solids to extract oil. Stir in 1 tsp fine sea salt to help stabilize and slightly season the oil. Optionally add the blanched chiffonade into the jar for additional visual herbiness. Chill and store refrigerated up to 2 weeks.

Place quartered strawberries in a nonreactive bowl. Add 3 tbs plain yogurt (or whey), 1 tbs sugar and 1 tsp salt. Mix gently so fruit is coated. Cover with a loose lid or cloth and leave at room temperature (18–24°C / 65–75°F) for 6–12 hours to develop a mild lactic tang — shorter time for gentle tang, longer for more pronounced. Once fermented to taste, refrigerate and use within 3–4 days. Reserve the fermentation liquid as a bright flavor component if desired.

Char lettuce

Heat a grill pan or cast-iron skillet to high. Brush cut sides of halved lettuces with a light film of neutral oil. Place cut-side down and char until dark grill marks appear and the edges show gentle blackening, about 2–3 minutes per side. Transfer to a plate to cool slightly.

Prepare aioli base

In a mortar or small bowl, mash the smashed garlic with a pinch of salt until a paste forms. Whisk the egg yolks with lemon juice and the garlic paste. While whisking vigorously, drizzle in the 3 tbs neutral oil to begin an emulsion.

Finish aioli with lime leaf oil

Once the base is starting to emulsify, whisk in the reserved lime leaf oil (3 tbs) in a slow stream until fully combined and thickened. Fold in charred lettuce (finely chopped) and adjust seasoning with up to 1 tsp salt. If aioli becomes too thick, thin with a teaspoon or two of the fermentation liquid from the lactic strawberries or a little water to reach desired consistency.

Pick and wash tulsi and sweet basil leaves; pat dry thoroughly. For a bright, herbal lift, reserve a few whole leaves. For additional texture, lightly chiffonade several leaves to mix into or sprinkle over the finished plate.

Segment the grapefruit using a sharp knife: cut away peel and pith, then cut between membranes to release segments. Thinly slice the wiri wiri pepper (remove seeds if less heat desired). Toss grapefruit segments with a pinch (1/4 tsp) fine sea salt and a few slivers of the pepper to lightly pick and brighten the fruit. Let sit 5–10 minutes for flavors to marry.

To assemble: spoon a few dollops of charred lettuce aioli onto the plate. Arrange lactic strawberries nearby (1–2 tbs per serving) and place grapefruit segments with a couple pepper slivers. Drizzle 1–1.5 tsp of lime leaf oil around and over components for aromatic lift. Scatter tulsi and sweet basil leaves, then sprinkle 2 tsp furikake across the plate for umami crunch. Finish with a light crumble (about 2 tbs) of grated white Sonora cheese over the dish. Taste and add a final tiny pinch of salt if needed.
