Strawberry Rhubarb Macarons: Late-Spring Recipe With a Tart Twist
Strawberry and rhubarb is April and May's signature duet — the rhubarb's sharpness keeping the strawberry honest. In a macaron, that pairing shines as a compote-swirled buttercream: fruity, tart, not too sweet. This recipe makes about 28 filled macarons and uses a real cooked compote (no flavor oils), because that's how we'd do it at the bakery.
Ingredients
Shells (Italian method for stability):
- 200g almond flour, finely ground
- 200g powdered sugar
- 148g egg whites, divided (74g + 74g)
- 200g granulated sugar
- 50g water
- Red gel coloring, one toothpick-scrape for a soft rose pink
Compote:
- 150g strawberries, hulled and chopped
- 100g rhubarb, cut into 1cm pieces
- 40g granulated sugar
- 1 tsp lemon juice
Buttercream:
- 150g unsalted butter, room temperature
- 90g of the cooled compote (fully drained of excess juice)
- 60g powdered sugar
- Pinch of salt
Step 1: Make the Compote First
The filling needs to be cold, so it comes first. Combine strawberries, rhubarb, sugar, and lemon juice in a small saucepan over medium heat. Cook 8–10 minutes, stirring, until the rhubarb collapses and the mix thickens to a loose jam. You should have about 110–120g. Press through a fine sieve to remove stringy rhubarb fibers — critical, because fibers in a piping bag are tiny clogs waiting to ruin your afternoon. Refrigerate until completely cold.
Step 2: The Shell Batter
Sift almond flour and powdered sugar together; mix in the first 74g of egg whites to form a paste, cover, and set aside. Cook granulated sugar and water to 118°C (244°F); meanwhile whip the second 74g of whites to soft peaks. Stream the hot syrup into the whipping whites and beat at high speed until stiff and glossy, adding color in the final minute. Fold one-third of the meringue into the paste vigorously to lighten, then fold in the rest until the batter ribbons slowly and passes the figure-8 test.
Step 3: Pipe, Rest, and Bake
Pipe 3.5cm rounds, bang trays firmly, pop bubbles, and rest until touch-dry, 30–45 minutes. Bake at 300°F for 14–16 minutes — but the Italian method is forgiving of slight variation; the giveaway is a firm, non-wobbling top. Cool fully on the tray before lifting. (Impatience here is how shells lose their bottoms, literally.)
Step 4: Buttercream With a Dam
Beat butter for 3 minutes until pale, then beat in powdered sugar and salt. Add the cold compote a spoonful at a time — if it's too loose, stop adding; fruit water is the enemy of pipeable buttercream. Assembly uses the dam method: pipe a ring of plain-ish buttercream around the shell edge, then spoon a small dot of looser compote-buttercream (or straight compote, a half-teaspoon) in the center. The dam seals the wet center so sandwiches don't slide.
Step 5: Mature for Flavor You Can't Fake
Seal filled macarons airtight and refrigerate 24 hours. This rest lets moisture equalize: shells turn chewy, and the strawberry-rhubarb flavor migrates into the almond crumb. Bring to room temperature 20 minutes before serving. The result is spring in two bites — bright, tart, pink, and gone faster than you expect. For parties, these pair beautifully with a variety box so guests can compare flavors.
Common Issues With Fruit-Compote Fillings
- Sliding shells: filling too wet — reduce compote further or use less
- Soggy bottoms after two days: too much straight compote in the center — the dam method keeps it contained, but respect the half-teaspoon limit
- Buttercream breaking: compote wasn't fully cold. If it splits, chill the bowl 10 minutes and re-whip
- Pale shells: natural pink shells always need a touch more gel than instinct says; baked color fades
