Nutrition notes
Tuna is an excellent source of lean protein, supporting muscle repair and satiety. It also provides vitamin B12, selenium and omega-3 fatty acids, nutrients that contribute to brain health, immune function and cardiovascular wellbeing.
Sesame seeds add calcium, magnesium and antioxidant-rich lignans, while the ponzu dressing provides bright citrus notes that balance the richness of the fish without relying on heavy sauces.
For best nutritional quality, choose sustainably sourced sashimi-grade tuna and avoid overcooking to preserve its delicate texture.
FAQs
Can I cook tuna all the way through?
Yes, although sashimi-grade tuna is traditionally served rare. Cooking beyond medium will produce a firmer, drier texture.
What is ponzu?
Ponzu is a Japanese citrus soy sauce made from soy sauce combined with citrus juice such as yuzu, lemon or lime. It adds a bright, savoury flavour that’s ideal with seafood.
What tuna should I buy?
Look for fresh sashimi-grade yellowfin or bluefin tuna from a reputable fishmonger if serving rare.
Can I make this ahead?
The dressing can be prepared up to three days ahead, but the tuna is best cooked immediately before serving.
