Peel the pear and apple and remove the cores. Chop the fruit, yellow onion, green onion, and garlic into small pieces.
1 Fuji Apple, 1 Pear, ½ cup yellow onion, 3 cloves garlic, 1 green onion
Add the chopped ingredients to the food processor. Add in the water and the soy sauce. Blend until smooth. The mixture will be grainy, but smooth it as much as you can.
5 tbsp water, 147 ml LOW SODIUM soy sauce
Heat a sauce pot over low-medium heat and add the mixture. Pour in the rice wine and brown sugar. Low simmer for ten minutes. Stir occasionally to prevent burning. Add the pepper. Continue to mix and simmer. Add in the cornstarch slurry during simmering to thicken the sauce more if you prefer. 1 ½ tbsp Rice Cooking Wine, 1 ½ tbsp brown sugar, Black Pepper, Cornstarch Slurry
Remove the sauce from the heat and let it cool down completely.
Add the cooled down sauce to a high power blender and blend until the sauce is smooth.
Store: Transfer your sauce into a clean jar or airtight container. It can be stored in the refrigerator for up to two weeks, allowing the flavors to meld beautifully.
