Vanilla ice cream:
Mix the cane sugar with the egg yolks in a glass bowl. Add the vanilla seeds. Whisk until fluffy.
Pour the milk and cream into a saucepan, add the de-seeded vanilla pods and bring to a boil.
Pour over the egg yolk mixture. Mix well and pour everything back into the pot. Now you have an anglaise.
Stirring, bring just below the boiling point (ideal is 85°). Do the test with a spatula: dip a spatula into the mixture and draw a line. If the line remains clearly visible without droplets forming, it's ready.
Strain if necessary. Cool in a double boiler with ice. Pour the anglaise into the ice cream maker (the ice element must be in the freezer for at least 24 hours) and let it churn for 30 minutes.
Crumble:
Put the ingredients for the crumble in a dish and mix everything together with your fingertips. Knead well between your hands until crumbly.
Finally, add the rainbow sprinkles. Spread evenly on a baking sheet lined with parchment paper and bake for 12 minutes at 170°.
Let cool.
Whip the cream stiff with coconut blossom sugar, put it in a piping bag.
Tips
Put the rest of the ice cream in a container and save in the freezer for 1 week. You can also use the unbaked rainbow crumble to make fruit crumble. 😉
