Raw Carob-Cashew Pudding or Mousse

1 cup raw cashews, soaked in room-temperature water overnight (if soaking for more than 10 hours, place in the refrigerator)
12-14 dried dates, soaked in room temperature water overnight (if soaking for more than 10 hours, place in the refrigerator)
2 tsp. carob powder
water or soymilk, as needed
1 tsp. pure vanilla extract, optional

After the nuts and dates have soaked for at least 6 hours, drain the nuts but not the dates. Pour the cashews, dates and soaking water, and carob into a blender. Blend over low speed until combined.
If the mixture seems too thick to blend, you can either blend smaller batches or add more liquid, a small amount at a time, to encourage the mixture to whirl round. Stop every few seconds and scrape down the sides, then blend again, continuing to blend at progressively higher speeds, until you have a perfectly smooth and creamy pudding. This may take 5-10 minutes. Unfortunately, a food processor isn’t going to get the mixture quite smooth enough, so you’re just going to have to wait.
