Made the smoothest flan with instant pot today! The trick is no direct water pressure on the cups. I used to just place the trivet and even placing towel on top then place flan cups on the towel. However, I still get a lot of bubbles. So I thought maybe if I put something else higher with holes then it might solve the problem. And it did! I used a steamer basket and flipped it upside down...lol
Need 8- 6oz molds: I used custard glass cups
3/4 cup sugar
1/4 cup +2 tbsp water
Cook sugar and water until caramelized. Divide into 8 molds.
Custard: (can use large eggs, reduce milk to 2 1/2 cup)
3 cups whole milk
3 whole eggs jumbo (200g total)
3 egg jumbo yolks (125g total)
1/2 cup sugar
1 tsp vanilla or rum
Boil milk until hot. While milk cooking, place eggs, yolks, sugar, and vanilla in a large bowl. Lightly whisk until mixture combined.
Now slowly add in the hot milk while whisking egg mixture. Mix until combined.
Strain mixture over a fine mesh strainer 3 times.
Prepare instant pot with trivet, flip steamer upside down on trivet. Add in 1 1/2 cup hot water.
Pour custard solution in caramel molds. Wrap with aluminum foil.
Will need to do in 2-3 batches since can't fit all in the pot.
Place molds on top of flipped steamer basket. Set manual pressure on LOW for 2 minutes. Then wait more 4 minutes L 00:04 and do quick release to remove all steam. Remove flan out of instant pot and repeat. Remove aluminum foil once out of pot. Add more water to pot each time.
Cool and refrigerate until serving.
