Uni Butter

How can I use uni butter? Our two suggestions are, mix the butter into pasta, or spread it over broiled fish. But honestly, the possibilities are endless!

  • 4.6 ounces uni
  • 1/2 pound unsalted butter softened
  • 2 tsp fresh lemon juice
  • sea salt to taste
  • 1 tbsp minced chives
  • 1 tsp black pepper
  • 1 pinch cayenne optional
  • wax paper


  • *note: Leave butter out for several hours until soft. This is very important. If you use cold butter, it won’t work.
  • Put Uni eggs in a bowl, and with an electric mixer, whip the eggs until they are smooth and velvety in consistency, similar to pancake batter. Set Aside. In a Large electric mixer, add the softened butter, and start mixing on the lowest setting. Slowly add the Uni mixture until its completely blended with the butter. Once it is blended, turn up the speed on the mixer to medium.
  • Add in lemon juice, salt, pepper, chives, and cayenne. When it is needed, scrape down the sides of the bowl with a rubber spatula. Continue mixing for 2-3 minutes until everything is well blended into a smooth, creamy consistency.
  • On a flat surface, lay down a good size sheet of wax paper. Place the Uni butter on the wax paper, and roll it into a log about 2 inches in diameter. Fold over the ends of the wax paper and roll it to seal.
  • Place the log in the refridgerator for a couple of hours to firm up. When firm, you can cut the butter into smaller pieces and keep it in fridge for a few days, or freeze the extra butter if you want to save it for another recipe in the future.


Be sure to taste before you add any salt.  Uni is now packaged in salt water which makes it pretty salty on it's own.
