Earl Grey Roll Cake (Tea-Infused Chiffon Cream Roll)
Instead of grinding the leaves into the batter, this roll steeps Earl Grey in warm milk and strains it. The sponge carries bergamot aroma without visible tea specks. The chiffon sheet gets its lift from a folded meringue and stays soft enough to roll. Rolling it once while still warm, paper and all, sets the curve so it is less likely to crack when filled later. The whipped cream is only lightly sweetened, leaving the tea as the main flavor.
