Mason Jar Butter

Makes 3 ounces, or almost 1 stick

• 1 cup full-fat heavy cream 
• 1 teaspoon full-fat sour cream 
• 1 (16-ounce) regular Mason jar 
• Cold water 

Pour the cream and sour cream into the jar, filling it halfway. Screw the lid on and shake the jar for 6–8 minutes. After the first 4 minutes, you’ll have whipped cream. Keep shaking until a lump has formed inside, and shake an additional 30–60 seconds after that.  

Remove the solids from the jar. The remaining liquid is buttermilk, which you can save for other recipes or discard.
