Sashi Beef – exceptional marbling.
Meat quality you can see before it even reaches the grill.
Sashi Beef from Finland is renowned for its distinctive intramuscular marbling. The finely distributed fat creates exceptional juiciness, tenderness and an intense beef flavour during cooking.
At tonWERK, Sashi Beef is one of the highlights of our steak selection.
Intense roasted flavours. Juicy centre.
High heat alone does not make a great steak.
Our meat is prepared in a special 800°C broiler at extremely high temperatures. What matters is the combination of meat quality, temperature, resting time and the perfect level of doneness. This creates intense roasted flavours while keeping the meat wonderfully juicy and tender inside.
