Chocolate tart filling
A ganache set in a pastry case. It needs to cut cleanly and stay soft in the mouth, which pulls the ratio in two directions.
A chocolate tart is a ganache poured into a baked case and left to set. The competing requirements are that it must cut without crumbling and melt in the mouth rather than feeling firm, and the ratio sits between those.
Around 3:2 chocolate to cream for dark is the usual compromise. Firmer cuts cleanly and eats heavy; softer eats beautifully and slumps when sliced.
Set at room temperature rather than in the fridge. Refrigeration firms the filling past the point where it melts properly, and a tart served cold from the fridge tastes of considerably less than the same tart at room temperature.
- What it is for
- To set a ganache in a pastry case so it cuts cleanly and eats soft.
- Working temperature
- 18–22°C — Setting and serving temperature. A refrigerated tart is firmer and tastes flatter; bring it back to room temperature before serving.
- Works with
- Dark chocolate, Couverture
Ratios
| For | Ratio | Note |
|---|---|---|
| Dark chocolate tart | 3:2 chocolate to double cream | Firm enough to cut, soft enough to melt. Move toward 2:1 for a firmer set. |
Method
1. Blind-bake and cool the case fully before filling.
Where people go wrong: Pouring into a warm case, which melts the pastry's butter and softens the base.
2. Make the ganache, cool it slightly, and pour into the case in one movement.
Where people go wrong: Pouring boiling-hot ganache, which traps air bubbles at the surface.
3. Set at cool room temperature for several hours rather than in the fridge.
When it goes wrong
| Symptom | Cause | Fix |
|---|---|---|
| Filling will not cut cleanly | Too soft a ratio, or served too warm. | More chocolate next time. A hot knife wiped between cuts helps in the meantime. |
| Filling tastes dull | Served straight from the fridge. | Cold suppresses aroma. Let it come to room temperature. |
