I saw this recipe it was so simple I had to try it! It was soo easy!
1 pound Unsalted Butter, Softened
1 cup Berries (Blackberries, Raspberries, Blueberries Ect)
Make the berry butter: in separate batches, whip 2 sticks of butter at a time on high using the whisk attachment. Switch to paddle attachment. Add 1/2 cup berries. Turn mixer on low for only about five seconds, just long enough for the berries to begin to mix in/break up, but not so long that it turns into a mess. Clean mixer bowl and attachments and repeat.
With each batch, turn mixture out onto a long sheet of plastic wrap set over a long sheet of foil. Use the wrap/foil to roll the butter into a cylinder: first seal the plastic wrap around the cylinder, then secure the foil around it. Twist the ends, gradually applying more pressure as you twist in order to make the cylinder taut.
Once it's a nice, neat cylinder of foil, place into the freezer for 30 minutes in order to quickly solidify it, then transfer it to the fridge until you're ready to use it. Butter should be nice and firm.
