Detailed Steps To Make Sweet Onion Sauce

Step 1: Gather Cooking Essentials

Collect a saucepan, whisk, measuring tools, and an airtight storage container for your homemade sauce.

• White sugar
• Corn syrup
• Vinegar
• Water
• Salt
• Dried minced onion
• Worcestershire sauce

Step 2: Blend Flavor Base

Pour all ingredients into the saucepan and whisk thoroughly until the mixture looks smooth and consistent.

Make sure no dry ingredients are clumping at the bottom of the pan.

Step 3: Bring to Rolling Boil

Place the saucepan over medium-high heat and continuously whisk the mixture.

Watch for bubbles to form and expand across the entire surface, indicating a full boil.

Step 4: Reduce and Simmer

Lower the heat to maintain a gentle simmer.

Keep whisking to prevent burning and allow the sauce to thicken naturally. The consistency should become slightly more viscous and glossy.

Step 5: Test Sauce Thickness

After about 5-7 minutes of simmering, the sauce will develop a syrupy texture. To check readiness, dip a spoon into the mixture – it should coat the back of the spoon without immediately running off.

Step 6: Cool and Store

Remove the saucepan from heat and let the sauce cool completely at room temperature. Once cooled, transfer to an airtight container and refrigerate.

The sauce will keep well for up to one week.

Expert Guidance To Nail Subway Sweet Onion Sauce

• Low-Sugar Alternative: Substitute corn syrup with stevia or monk fruit sweetener, reducing overall sugar content while maintaining similar consistency and flavor profile.
• Spicy Southwest Remix: Add cayenne pepper or chipotle powder to introduce a smoky heat that transforms the original sweet onion sauce into a zesty condiment.

Great Foods To Pair With Sweet Onion Sauce

• Pair with Grilled Chicken Sandwich: Drizzle this sweet onion sauce over a juicy grilled chicken sandwich for a flavor-packed lunch that brings tangy and savory notes together perfectly.

Instructions

1. Select a medium saucepan and pour all ingredients together, stirring vigorously with a whisk to ensure complete and smooth integration of components.
2. Apply medium-high heat, continuously whisking the mixture until it reaches a rolling boil, preventing any potential ingredient separation or lumping.
3. Once boiling, immediately reduce heat to low, maintaining a gentle simmer while consistently stirring for approximately 5 minutes to develop a rich, cohesive sauce consistency.
