Fold

Combine mixtures lightly while preventing loss of air, such as folding beaten egg yolks into beaten egg whites for a soufflé or folding liqueur into whipped cream. To fold, gently spoon or pour one mixture over another mixture in a bowl. Using a rubber spatula, first cut down vertically through mixtures. Next, slide spatula across bottom of bowl and up the side, turning the bottom mixture over the top mixture. Rotate bowl one-fourth turn, and repeat this down-across-up motion. Continue mixing in this way just until mixtures are blended.
