Ingredients

  • 2 cups heavy cream
  • 1 cup milk
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1 pinch of table salt
  • 1 jalapeno pepper, seeded and chopped small. You can leave some seeds in to make it a bit hotter.
  • 5 large egg yolks
  • Juice of one lime
  • Zest from 3 limes

Instructions

  1. Combine 1 cup of the heavy cream and the 1 cup of milk with the sugar in a sauce pan over medium heat. Stir until the sugar is dissolved and small bubbles start to form at the edge of the pan. This should not take more than 4 minutes. Do not let this go to a boil.
  2. Add in about 3/4 of the chopped jalapeno and remove the pan from the heat. Cover it and let it sit for at least an hour. Taste the mixture, if t is NOT spicy hot enough then let it sit a while longer, if it is go to your next step.
  3. In a large bowl, add ice and water, place a smaller bowl inside the large bowl with the ice and water. Pour in 1 cup of the heavy cream and allow to cool.
  4. Separate the egg yolks from the egg whites. Place the yolks in a bowl and whisk in about 1/2 the warm cream from the pan. Pour this back into the the same pan and return the pan to the heat for about 4 to 6 minutes to thicken the mixture slightly. Do not let this come to any degree of a boil, if you do it will cook the eggs which will ruin the ice cream.  If you have an instant read thermometer the done temp is around 170° to 180°.
  5. Once that temp is reached , immediately pour this into the now COLD heavy cream that is in the bowl sitting in ice water and whisk together . Monitor the temp and keep mixing until the temp of the cream mixture reaches 70°
  6. Mix in the lime juice at this time then cover the bowl with plastic/cling wrap and place in the refrigerator for at least 4 hours or over night.
  7. When you are ready to churn your custard, pour it into the ice cream maker and run it as the instructions describe.
  8. In the last minute or so of freezing add in the remaining chopped jalapeno peppers and the lime zest to make sure it gets folded into the mixture well.
  9. Once this is finished, transfer it into an airtight container and put it in the freezer for 2 hours or up to a couple of weeks.
