This rich, velvety, old-fashioned, homemade custard made with raw milk & free-range egg yolks is so simple & delicious! It’s perfect plain, in parfaits, and as the base of custard pies!
Slowly pour the milk and egg yolk mixture into the sugar/flour mixture while whisking. Turn the heat up to medium-low once everything is whisked together.
Bring the custard to a boil, whisking the whole time. Allow the custard to boil for 1 minute. Then add the butter. Continue whisking for 1 more minute.
