Combined 1L heavy cream with 1/2L whole milk, 6 egg yolks, 3/4 tsp salt, and 292 grams of sugar on the stove top, and slowly heated it to 81°C

While it was heating, I mashed and roasted 4 ripe bananas. At 78°C I bloomed 6 grams of gelatin in 30ml of cold water.

At 81°C, I added the mashed bananas, gelatin, 30ml of rum, and 1 tsp of vanilla.

Immersion blended it all for 90 seconds, strained, and chilled overnight. Froze and churned the next day in my Whynter stainless.
