Sik hye 식혜

1. https://mykoreankitchen.com/sikhye/ : Most comprehensive recipe, describes using the course malt barley, the powder, and the teabag
2. https://www.maangchi.com/recipe/sikhye: I mostly used this method but it also describes making it a slushie

Generally, the recipes are pretty aligned. The difference between these two and other recipes is whether they use the course malt barley or the powdered type. While Maangchi uses the powder, Korean Kitchen thinks that the powdered type doesn't help the rice grains to float to the surface. However, I used the powder and didn't have a problem so I think it's because Korean Kitchen left the powder in a cheesecloth.

Ingredients
1 cup malted barley
18 cups of water
1 cup of cooked rice (short grain or glutinous rice)
1 cup sugar
pine nuts and red dates for garnishing (optional)

Method
1. Add the water to the malted barley and stir well. Soak the malted barley 2 to 3 hours in a large bowl and let the sediment settle. The clear water should have separated to the top.
2. Meanwhile, cook the rice with slightly less water so that it's a bit undercooked.
3. Once the rice is cooked, carefully strain the malted barley water with the help of a cheesecloth, into the rice. The sediment should have settled at the bottom. Be careful not to stir up the sediment at the bottom.
4. With the sediment, pour in the remaining 4 cups of water and leave to steep.
5. Leave to ferment in the rice cooker using the Keep Warm function at between 55 to 60 deg C. After 4 hours, check to see if a dozen or so rice grains have floated to the top. If they have, sik hye is ready. It only took me 3 hours. If grains haven't, leave it to ferment for another hour.
6. Once the grains has floated, again carefully pour the malted barley water into the pot, once again, with the help of the cheesecloth. Throw away the sediment.
7. Bring the sik hye to a boil and add the 1 cup of sugar to dissolve. Skim off the foam and boil for 10 minutes.
8. Once finished boiling, leave to cool. Strain off the rice grains and wash it in cold water to wash off the starch. Keep the rice grains in a separate air tight container with some cold water. If the grains are left in the sik hye, the whole liquid turns grey.
10. Strain off the sik hye into a glass bottle.
11. Serve hot or chilled in a bowl, topped with red date and pine nuts if using, and about two tablespoons of rice grains.
12. Keep the rice grains and sik hye refrigerated for up to a week. Once it goes sour, it's time to throw it away.

Recipe feedback
The grains delighted me because they felt so light on the tongue. I was expecting porridge-type of stodgey rice but the grains here were light and fluffy!
