Why it works: Coffee and cocoa work together. They rank in the top 3% of all ingredient pairs, and cooks put them together in 91 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Frozen Chocolate Roll
Ingredients
Directions
Prepare the batter
Heat oven to 350°F.
Melt chocolate with water and coffee powder in the top of a double boiler over hot water. Stir until smooth.
Remove from heat and cool slightly.
Beat egg yolks with sugar in a large bowl until fluffy. Stir in the cooled chocolate; mix thoroughly.
Beat egg whites until stiff but not dry; gently fold into the chocolate mixture.
Grease a jellyroll pan with vegetable oil and cover with a sheet of waxed paper extending 1" beyond the ends of the pan. Spread the batter evenly over the paper.
Bake and cool
Bake 17–18 minutes; the cake will puff up and the surface will have a dull finish when done. Do not overbake.
Soak a layer of paper toweling in water and wring dry; place it over the top of the cake. Cover with a layer of dry paper toweling.
Let stand 20 minutes. Remove the paper toweling and loosen the edges of the cake.
Sprinkle the top of the cake with cocoa.
Soak a dishtowel in water and wring dry; stretch it taut over the cake and invert it. Lift off the pan and carefully peel off the waxed paper.
Roll up the towel with the cake inside it, along the long edge. Let stand 5 minutes.
Fill and finish
Unroll the cake and spread softened vanilla ice cream evenly over the surface.
Re-roll the cake without the towel; place seam‑side‑down on a long flat platter or jellyroll board. Don’t worry if the cake cracks a bit.
Using a spatula or pastry tube with a star tip, cover the roll with whipped cream.
Place in the freezer until solid, at least 4–5 hours.
Remove from the freezer 15 minutes before serving.
This may be made in advance and stored in the freezer in an airtight plastic bag up to 2 weeks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the cake its airy, light structure, while yolks add richness.
- Semi-sweet chocolate
- Provides the main chocolate flavour and, once cooled, body to the batter.
- Superfine sugar
- Sweetens the batter and helps the yolks whip into a stable, fluffy base.
- Vanilla ice cream
- Softened, it forms a cold, creamy filling that sets firm when frozen.
- Heavy cream
- Whipped, it forms a light outer coating that adds richness and softness.
The step that matters
Do not overbake the cake. Overbaking dries out the thin sponge and makes it crack and crumble when rolled. Pull it out when the surface looks dull and the cake has puffed.

How well each one fits the dish's main ingredients (chocolate, coffee, egg, sugar, vanilla, cream):
