Ingredients
- 25 Milliliters lemon juice
- 40 Grams pitted black olives (chopped)
- 200 Grams arugula
- 1 Tablespoon fresh rosemary (finely chopped)
- 4 tuna steaks
- potato wedges (to serve)
- 1 cup commercially prepared mayonnaise (replaces raw yolk emulsion)
Instructions
- For food safety, use store-bought pasteurized mayonnaise as a base for the olive sauce instead of raw egg yolks unless making a verified pasteurized-egg version. Stir chopped olives and lemon juice into 1 cup mayonnaise, thinning if needed.
- Brush tuna steaks lightly with olive oil and sprinkle with rosemary and pepper.
- Sear or grill tuna to your preferred doneness; for higher-risk diners cook seafood to 63°C / 145°F. Use clean utensils and avoid cross-contamination.
