Pour the milk in a small pot. Over medium-high heat, bring the milk to an almost simmer (around 203 °F / 95 °C), and immediately remove it from the heat. Do not let it boil!
1 cup (240 ml) unsweetened cashew milk
Add the tea bag, put a spoon or something on top so that the bag doesn’t float at the top, and let it steep for 5 minutes.
1 chai tea bag
Meanwhile, mix together the pumpkin, maple, pumpkin pie spice or cinnamon, starch and vanilla in a small bowl.
2 1/2 tablespoons (38 grams) pumpkin puree, 1 1/2 tablespoons maple syrup, 1 teaspoon pumpkin pie spice, 1/2 teaspoon cornstarch, 1/2 teaspoon vanilla extract
When the tea is done steeping, press the tea bag up against the side of the pot with a spoon to make sure you extract as much as you can from the tea bag.
Whisk the pumpkin mixture into the tea mixture until totally combined. If it's hot enough for you, pour into a cup and top with frothed cashew milk, if desired. If you'd like it warmer, you can reheat it over medium heat on the stovetop. Don't let it simmer!
