How to Make Onion Boil
Prepare the onions: Peel the onions and trim the tops and bottoms. You can leave them whole for a more rustic look or cut them in half if you prefer faster cooking.
Mix the base: In a large pot, combine the 4 cups of water, soy sauce, apple cider vinegar, brown sugar, olive oil, minced garlic, grated ginger, black peppercorns, and optional red pepper flakes. Stir well until the sugar dissolves completely.
Bring to a boil: Heat your pot on medium-high and bring the mixture to a rolling boil, allowing those enticing aromas to fill your kitchen.
Add onions: Carefully place the prepared onions into the pot, making sure they are submerged in that delicious mixture.
Simmer gently: Reduce the heat to low, cover the pot, and let the onions simmer for 30 minutes. They should become tender and soak up all the flavorful goodness.
Drain the onions: Once they’re cooked to perfection, gently remove the onions and let them drain briefly. This ensures they keep their beautiful shape and texture.
Serve with flair: Enjoy the onions warm, garnished with fresh herbs like thyme or parsley to impress your family or guests!

Tips for the Best Onion Boil
Even cooking: Use onions of similar sizes to ensure they cook evenly. This will prevent some from being too soft while others remain firm.
