Full Ingredients

Base and Flavor

• 1 cup (240 ml) 100% pineapple juice
• 1/3 cup (80 ml) ketchup
• 1/3 cup (80 ml) rice vinegar
• 1/3 cup (70 g) packed light brown sugar
• 2 tablespoons (30 ml) low-sodium soy sauce
• 2 teaspoons (6 g) grated fresh ginger
• 2 teaspoons (6 g) minced garlic
• 1/4 teaspoon crushed red pepper flakes (optional)

Thickener

• 2 tablespoons (16 g) cornstarch
• 2 tablespoons (30 ml) cold water

Optional Finishing

• 1 teaspoon (5 ml) toasted sesame oil for shine (optional)
• Fine sea salt to taste, only if needed

Step-by-Step Instructions

Step 1: Prep your aromatics

Grate the ginger and mince the garlic finely so they soften quickly and disappear into the sauce. Measure all the wet ingredients into separate cups and whisk the cornstarch with cold water to make a smooth slurry. Keep the slurry cold and re-whisk it right before you add it so it stays lump-free.

Step 2: Build the base

In a nonreactive medium saucepan (stainless steel or enameled), combine pineapple juice, ketchup, rice vinegar, brown sugar, soy sauce, ginger, garlic, and red pepper flakes (if using). Whisk until the sugar is mostly dissolved, about 30 seconds.

Step 3: Simmer to bloom flavors

Set the pan over medium heat and bring the mixture to a gentle simmer—look for small bubbles around the edges—about 200–205°F (93–96°C). Stir occasionally for 2–3 minutes to dissolve the sugar fully and soften the ginger and garlic.

Step 4: Thicken with a slurry

Re-whisk the cornstarch slurry. With the sauce at a steady simmer, slowly drizzle in the slurry while whisking constantly. Continue simmering and whisking until the sauce turns glossy and thick enough to coat the back of a spoon (nappe consistency), 2–4 minutes. Avoid a hard boil, which can make starch look dull.

Step 5: Adjust and finish

Taste and tweak: add 1–2 teaspoons rice vinegar if you want more bite, or 1–2 teaspoons brown sugar for extra sweetness. If the sauce is thicker than you like, whisk in 1–2 tablespoons water (or pineapple juice) to loosen. For a subtle sheen, stir in toasted sesame oil.

Step 6: Cool, jar, and store

Remove from heat and let cool 10–15 minutes; it will thicken slightly as it cools. Strain through a fine mesh sieve if you prefer an ultra-smooth sauce. Transfer to a clean glass jar, label, and refrigerate. The sauce will be pourable when warm and spoonable when cold.

Pro Tips

• Keep the slurry cold and add it slowly while whisking to prevent lumps.
• Simmer gently; a rolling boil can thin the starch and mute the glossy finish.
• For ultra-smooth texture, strain the sauce before jarring.
• Color boost without dye: whisk in 1/2 teaspoon sweet paprika or a pinch of Korean gochugaru.
• Remember it thickens as it cools—aim for slightly thinner than your target on the stove.

Variations

• Spicy Sweet-and-Sour: Add 1–2 teaspoons sambal oelek or 1 teaspoon gochujang with the ketchup.
• Orange Twist: Replace pineapple juice with fresh orange juice and add 1 tablespoon lemon juice; reduce brown sugar to 1/4 cup.
• Chunky Pineapple: Stir in 1/2 cup finely diced pineapple after thickening for a textured dipping sauce.

Storage & Make-Ahead

Refrigerate in an airtight jar up to 1 week. Freeze up to 2 months; thaw overnight in the refrigerator. Rewarm gently over low heat, whisking and adding 1–3 teaspoons water or pineapple juice to loosen as needed. For best texture, avoid boiling once thickened.
