Step 1Pour the sake into a glass container. Wash the strawberries. Remove the stems and cut the berries in half lengthwise or quarters if large. Add the strawberries to the sake and stir. Seal the container.
Step 2Let sit at room temperature for 2 to 4 days, tasting after the second day. Note: The fruit will lose its color, but that's OK.
Step 3To serve, refrigerate until chilled, then strain out the berries. Best served well chilled but not on ice.
