Pro Tips

• For an ultra-silky texture, strain the custard mixture through a fine-mesh sieve before pouring it into the ramekins to remove any small lumps.
• Don’t over-beat the mixture. Mix just until the are combined and creamy to prevent a foamy or airy texture.
• Experiment with flavors by swapping vanilla for almond extract, adding a pinch of nutmeg, or grating fresh orange zest into the custard base.
• The custards are done when the edges are set but the center still has a slight jiggle. They will continue to firm up as they cool and chill.
