This week’s recipe features another tuber: the purple yam. Purple yams are commonly used in the Philippines, where they are known as ube. In North America, you can buy purple yams at most Asian green grocers. You can also find them in some conventional grocery stores, alongside potatoes and sweet potatoes. Purple yams have a reddish-brown skin and the most delightful purple insides.
This is a super simple ice cream recipe. You puree peeled and boiled yams with some coconut milk, soy milk, sugar, and a pinch of salt and – ta da! - your custard is done and ready for chilling. Yes, finally, another dairy-free and egg-free ice cream recipe!
I had a bit of a chuckle as I was pouring the custard into the ice cream maker. It was super thick and goopy because of the richness of the coconut milk and the starch in the yams, and the colour reminded me of McDonald’s Grimace character. As for taste, the Official Taster claims it’s “gentle”. Huh??? I will interpret that to mean “an ice cream with a soft, pillowy texture, wonderful coconut flavour, and subtle undertones of purple yam”.
Keep in mind this ice cream freezes up quite hard overnight. Enjoy it as soon as it is chilled to serving consistency. If you need to freeze it longer, give it a good 15 to 20 minutes on the counter to warm up before scooping.
Purple Yam and Coconut Ice Cream (makes about 1.5 L)
2 cups of purple yams, peeled and cut into 1 inch pieces
1 – 13.5 oz (400 ml) can coconut milk
1.5 cup soy milk (or substitute dairy milk)
1/2 cup sugar
Pinch of sea salt
- Place the yams into a medium-sized sauce pan, cover with water, and bring to boil. Let simmer for about 20 minutes, until the yams are fork tender. Drain the yams, reserving 1/4 cup of the cooking water.
- Tip the yams and the reserved cooking water into a blender and puree until smooth.
- Add the coconut milk, soy milk, sugar, and salt into the blender. Puree until very smooth.
- Chill overnight in the fridge.
- Pour the custard into an ice cream maker and prepare according to the manufacturer’s instructions.
