Ingredients
The Strawberry Base
- 2 lbs (900g) fresh or frozen strawberries, hulled (frozen used directly from frozen)
- ½ cup (100g) granulated white sugar
- ½ cup (120ml) water
- Zest of 1 large lemon (added to slow cooker)
The Lemon (added after cooking)
- ¾ cup (180ml) fresh lemon juice (4–5 large lemons) — never bottled
For the Cold Version
- 1½–2 cups (360–480ml) cold still or sparkling water, to taste
- Ice for serving
For the Warm Version
- ½–1 cup (120–240ml) warm water, to taste
Optional at Serving
- Additional sugar, honey, or simple syrup to taste
- Lemon wheels, fresh strawberries, mint for garnish
Instructions
Making the Strawberry Base (both versions)
- Load the slow cooker. Add the strawberries, sugar, water, and lemon zest to the slow cooker. If using frozen strawberries, add them directly from the freezer — no thawing needed. Stir briefly to combine.
- Cook. Set the slow cooker to LOW and cook for 2 hours, until the strawberries have completely broken down, released all their juice, and the liquid is a deep, vivid red. The mixture will look like a loose compote. Do not lift the lid during cooking.
- Strain. Set a fine mesh strainer over a large bowl or pitcher. Pour the strawberry compote into the strainer and press firmly with the back of a spoon to extract every drop of juice. Work thoroughly — the more juice extracted, the stronger and more flavorful the base. Reserve the pressed pulp for another use (see notes).
- Taste the base. Taste the strained strawberry syrup before adding lemon juice. It should be sweet and intensely strawberry-flavored. Adjust sweetness with additional sugar or honey if needed.
For the Warm Version
- Return to slow cooker. Pour the strained strawberry base back into the slow cooker on KEEP WARM. Add the fresh lemon juice and ½ to 1 cup of warm water to dilute to the desired strength. Stir to combine. Taste and adjust — more lemon for tartness, more honey for sweetness.
- Serve warm. Ladle into ceramic mugs. Garnish with a lemon wheel, a fresh strawberry, and a sprig of mint. Serve immediately.
For the Cold Version
- Combine and chill. Pour the strained strawberry base into a large pitcher. Add the fresh lemon juice and 1½ to 2 cups of cold still water (or sparkling water added per glass at serving). Stir well. Taste and adjust sweetness and tartness.
- Refrigerate. Refrigerate for at least 2 hours until completely cold. The flavor improves slightly overnight.
- Serve over ice. Fill tall glasses with ice. Pour the cold strawberry lemonade over. Garnish with a fresh strawberry on the rim and a lemon slice. For a sparkling version, top each glass with cold sparkling water just before serving.
Notes
- Frozen strawberries go in from frozen. No thawing required. They release more liquid as they thaw during the cook, which contributes to the base volume naturally. Thawed frozen strawberries are mushier and harder to strain than ones that went in frozen and cooked slowly.
- Do not add lemon juice to the slow cooker. For the cold version, lemon juice added to the slow cooker for a 2-hour cook loses its fresh, bright character entirely. It goes in after straining. For the warm version, it goes in after the cook on KEEP WARM — the low temperature preserves its brightness.
- Strain firmly. The pressed strawberry compote holds a significant amount of juice that casual straining misses. Press firmly and repeatedly with the back of a large spoon until the pulp in the strainer is dry and pale. Every drop of juice extracted is concentrated flavor.
- The pulp is not waste. Pressed, sweetened strawberry pulp spread on toast is a two-minute jam. Swirled into plain yogurt it becomes a fruit-on-the-bottom yogurt of extraordinary quality. Blended into a smoothie it adds concentrated strawberry flavor. Do not discard it.
- Two pounds of strawberries is the correct quantity. The instinct when making a fruit-based drink for the first time is to wonder if two pounds is too much. It is not. Strawberries release a large proportion of their weight as water during cooking, and that water dilutes the base. Two pounds produces enough concentrated syrup for a full batch that still has strong strawberry flavor after dilution.
- For the cold version, refrigerate fully before serving. Warm lemonade poured over ice produces a diluted, temperature-inconsistent drink immediately. Two hours in the refrigerator produces a cold lemonade that is consistently flavored and properly chilled throughout.
- Fresh lemon juice is the ingredient. In a drink with two primary flavors — strawberry and lemon — the quality of both is directly detectable. Bottled lemon juice has a cooked, flat quality that is immediately apparent in something this simple. Squeeze the lemons fresh.
