Sous-vide Vanilla Ice Cream-Birdy

This is a traditional ice cream made with an egg-custard base, what my family called frozen custard. It is a bit of a hassle to cook the custard since it is easy to overcook the eggs when doing it on the stovetop and requires constant attention. So it was a surprise when I discovered that the base can apparently be cooked accurately and easily using the sous vide method. This can be done in an Instant Pot Duo Evo Plus following the manual for sous vide directions.

INTRODUCTION: SOUS-VIDE ICE CREAM

As a kitchen gadget freak, I acquired a sous-vide machine a few years ago when they were all the rage. I used it a few times but as we aren't great consumers of steaks or chops I wasn't that smitten. My kitchen gadgets have been in store for the last year while we moved house, so the sous-vide recently emerged from a box. And I thought as it was summer, I would try using it to make the custard for ice cream. So here's the story...

This instructable is for fellow kitchen gadget freaks. You need a sous-vide machine, an ice cream maker, and a stick blender!

STEP 1: INGREDIENTS

4 egg yolks
70 g (1/3 cup) sugar
Pinch of salt
Vanilla pod or extract - I used half a pod and a teaspoon of vanilla bean extract
175 ml (2/3 cup) milk
175 ml (2/3 cup) double (heavy) cream

(I found the same proportions in several recipes on the Internet)

STEP 2: MAKE THE CUSTARD MIXTURE
Put everything in a food processor or blender and process to mix. Transfer to a zip-lock freezer bag. Plunge bag in a sink full of water and squeeze the air out, then seal the bag.

STEP 3: COOK THE CUSTARD
Pre- heat the sous-vide water bath to 85 deg C/ 185 deg F. Put the bag of custard in, making sure the custard is below the water level. Cook for 1 hour, shaking the bag every 20 minutes to ensure mixing. Plunge the bag into a bowl of iced water, then chill in the fridge overnight.

STEP 4: CHURN THE ICE CREAM
Don't panic if the custard looks lumpy! Transfer to a jug and use a stick blender to blend it to a smooth custard. Pour into the ice cream maker and churn until done. Freeze.

STEP 5: ENJOY YOUR ICE CREAM
The result is very smooth - excellent ice cream.
