Sweet Onion Sauce Ingredients
The ingredients used in this sauce are simple and fresh. Once you have got all the ingredients ready it just takes minutes to come together. Here’s all you need:
- Onion: any sweet variety;
- Garlic: just a touch, to enhance the flavor;
- Vinegar: plain white distilled vinegar and balsamic vinegar;
- Granulated Sugar: you can also use brown sugar;
- Cornflour: cornflour or cornstarch to thicken the sauce;
- Black pepper powder: freshly ground is best;
- Nigella seed(also called kalonji): available in Asian grocery stores. Tastes like oregano and onion mix. It adds a hint of extra flavor. I like the flavor but you can totally choose to skip it;
- Lemon juice: fresh;
- Salt: regular table salt;
- Water: cold filtered water;
Preparations Step By Step
- Peel the onion and garlic, roughly chop them, and blend until look smooth. Squeeze the juice using a muslin cloth and transfer to a pan or pot.
- Heat up the pan. Add in water along with sugar, salt, white vinegar, balsamic vinegar, black pepper, nigella seeds, and bring the mixture to a boil until sugar dissolves.
- Whisk ¼ cup water and cornflour together in a bowl, and make a slurry.
- Add in cornflour slurry and stir continuously over medium flame until the sauce thickens and looks glossier.
- Remove from heat and add lemon juice. Stir to mix and allow the sauce to come to room temperature.
- Store in an airtight container in the refrigerator and use when needed.
How to store
