1. Combine all ingredients, except for lemon juice, in a large saucepan and bring it to a boil.
2. Once boiling, reduce heat to low and simmer for 30 mins, stirring occasionally.
3. After 30 minutes, remove the mixture from the stove, stir in lemon juice and let it cool. Once cool, you can pour your butter into into airtight jar(s) and store in refrigerator for up to for two to three weeks. You can also keep it frozen for up to a year!
