This sweet compound butter is flavored with fresh mashed blackberries and a touch of powdered sugar for a fruity and lightly sweet option for toast, rolls, biscuits, crêpes, or cornbread.
Add the blackberries to a medium size bowl. Use a fork or a potato masher to smash the berries until they have separated into seeds, flesh, and juice.
12 small to medium fresh blackberries
Use a fine mesh sieve to strain the seeds and flesh from the juice. You should have about ¼ cup of liquid once everything has been pushed through. Discard2 the seeds and flesh.
Add the softened butter and powdered sugar to the strained blackberry juice and use a handheld mixer to beat everything together until it is smooth and fluffy. You can also use a stand mixer fitted with the paddle attachment, if you prefer.
½ cup (113g) unsalted butter1, 3 Tablespoons (23g) powdered sugar
The butter is ready to use immediately but should be kept in the refrigerator for long term storage. You can keep it in a serving dish or roll it into a log wrapped in plastic wrap for a more "presentable" aesthetic, or keep it in a lidded container in the refrigerator. Chilled butter can be kept in the refrigerator up to 2 weeks or in the freezer up to 6 months.
Notes
Unsalted butter: I like this compound butter without salt, so if you prefer salted butter, you can use that in this recipe. If you use unsalted butter, taste it, and would prefer a saltier taste, you can add ¼ teaspoon to the butter and re-beat the mixture until it is fully incorporated. You can also use any nondairy butter you like!
Discard: if you would like the seeds and flesh in your butter, that is at your discretion. Some people like the authentic texture, but my preference is to leave them out for a smooth butter.
