Classic French Strawberry Fraisier
Kirsch-soaked génoise sponge, fresh Gariguette strawberries and luscious vanilla mousseline cream

Heritage & Historical Context
The quintessential French springtime entremets. Fraisier marries the featherlight texture of ribbon-whipped génoise, the fragrant acidity of fresh strawberries, and the architectural stability of vanilla mousseline cream that unmolds into crisp razor-sharp edges.
Invented in its modern architecture during the 1960s by Gaston Lenôtre, it transformed French celebratory pastry by replacing heavy buttercream with airy mousseline and showcasing whole fresh fruit.
Step-by-Step Laboratory Protocol
4 stepsBaking the génoise sponge
Whisk eggs and sugar over gentle double boiler to 50°C, then whip on stand mixer until completely cooled to thick ribbon stage. Fold in sifted flour gently. Bake 20 min at 175°C. Slice into two 20 cm discs.
Lining the ring with strawberry halves
Line inside of ring with acetate strip. Place first génoise disc soaked with kirsch syrup. Arrange strawberry halves upright with cut sides pressed flat against acetate all around.
Piping mousseline and layering
Pipe mousseline firmly between each strawberry half to avoid visible voids. Pack center with diced strawberries. Cover with cream, seat second soaked sponge disc.
Setting and green marzipan crown
Refrigerate at least 4 hours to firm. Roll thin disk of pastel green or rose almond marzipan over top. Lift ring and peel off acetate strip smoothly.
Chef's Technical Rules
- Select strawberries of strictly calibrated identical size for a pristine patisserie finish.
- Smear mousseline firmly against acetate between berries to eliminate air holes along the periphery.
Troubleshooting & Solutions
| Symptom | Root Cause | Corrective Action |
|---|---|---|
| Cream collapses when acetate collar is pulled away | Mousseline lacked required butterfat or chilling time was too brief | Chill a full 4 hours at 4°C so butter solids solidify the architecture |
