Ingredients for Cham Sauce
Nine simple ingredients create this bold, balanced Vietnamese dipping sauce for any dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Hoisin Sauce 🥫 | ½ cup | Thick, sweet soy-based sauce |
| Peanut Butter 🥜 | ½ cup | Creamy, unsweetened preferred |
| Rice Vinegar 🍚 | 2 tbsp | Mild, slightly sweet vinegar |
| Soy Sauce 🥫 | 2 tbsp | Low-sodium if preferred |
| Water 💧 | 2 tbsp | To thin sauce as needed |
| Granulated Sugar 🍚 | 1 tbsp | Adjust to taste preference |
| Garlic Clove 🧄 | 1 clove | Minced finely for maximum flavor |
| Lime Juice 🍈 | 1 tbsp | Freshly squeezed for brightness |
| Sriracha Sauce 🌶️ | 1 tsp | Adjust for desired heat level |
The hoisin and peanut butter are non-negotiable—Koon Chun or Lee Kum Kee for hoisin, Smucker’s Natural or Crazy Richard’s for peanut butter give consistent results. Look for hoisin with a deep mahogany color and peanut butter with just peanuts and salt (no added sugars). Most Asian markets stock these, but well-stocked supermarkets carry them too. Fresh garlic cloves should be firm, not shriveled.
No hoisin? Substitute with equal parts oyster sauce plus a touch of molasses—though authentic hoisin is recommended. Creamy almond butter can stand in for peanut butter at one-to-one ratio. Rice vinegar is milder than white vinegar—apple cider vinegar works as backup. For extra umami, add half a teaspoon of fish sauce (optional, but traditional for depth).
Sauce thickens as it sits. Thin with warm water, 1 tsp at a time. Stores in an airtight container in the fridge for 1 week. Stir well before each use as ingredients may separate. Freezing not recommended—textures change unfavorably.

Step-by-Step Instructions for Cham Sauce
This straightforward method ensures a perfectly balanced dipping sauce with authentic Vietnamese flavors.
Step 1: Combine the Base Ingredients
In a medium bowl, whisk together the 0.5 cup Hoisin Sauce and 0.5 cup Peanut Butter until smooth. The peanut butter should be creamy for the best texture, though natural varieties work if stirred well first. This forms the rich, nutty foundation of your sauce.
If the mixture seems too thick at this stage, resist the urge to thin it yet. The remaining ingredients will adjust the consistency. Ensure no lumps remain, as they’ll affect the final texture of the finished product.
Step 2: Incorporate the Acidic Elements
Add the 2 tbsp Rice Vinegar, 2 tbsp Soy Sauce, and 1 tbsp Lime Juice to the bowl. These ingredients provide the bright, tangy contrast that defines cham sauce. Use low-sodium soy sauce if you prefer to control the saltiness of your final dish.
Whisk vigorously for 30-45 seconds until the mixture becomes uniform. You’ll notice the color lighten slightly as the vinegar and lime juice emulsify with the thicker base ingredients. The sauce should now have a glossy sheen.
Step 3: Sweeten and Season the Mixture
Stir in the 1 tbsp Granulated Sugar and 1 clove Garlic Clove (minced finely). The sugar balances the acidity and saltiness, while the garlic adds the essential aromatic depth. Press the minced garlic against the bowl with the back of your spoon to release its oils.
At this point, taste and adjust the sweetness if needed. The sugar should complement, not overpower, the other flavors. Remember that the sauce will mellow slightly as it rests, so err on the side of slightly more acidity now.
Step 4: Adjust Consistency and Heat
Add the 2 tbsp Water and 1 tsp Sriracha Sauce, then whisk to combine. The water creates the ideal dipping consistency—thick enough to cling to fresh rolls but fluid enough to drizzle. The sriracha adds subtle heat that builds gradually.
For a smoother texture, let the sauce rest for 10-15 minutes at room temperature. This allows the flavors to meld completely. If you prefer more heat, you can add additional sriracha in ¼ tsp increments, tasting as you go.
Pro Tips For Making Cham Sauce
- Warm the Peanut Butter: Microwave the peanut butter for 10-15 seconds before mixing—it blends into the hoisin and soy sauce way more smoothly than cold, clumpy PB straight from the jar.
- Thin Gradually: Add water a tablespoon at a time while whisking; I learned this the hard way after turning my first batch into a watery mess by dumping it all in at once.
- Taste Before Serving: After mixing, let it sit for 5 minutes then taste again—rice vinegar’s sharpness mellows, and you might find you need a touch more soy or hoisin to balance it.
- Use Creamy PB: Skip the natural or crunchy peanut butter here—creamy blends in faster and gives that silky texture cham sauce is known for.
Make-Ahead Tips for This Dish
Prep Ahead Strategy
This sauce actually tastes better after resting, so I always prepare it 1-2 days in advance. The flavors meld beautifully in the fridge, and the garlic mellows to a perfect subtle warmth. Just whisk before serving to recombine any separated ingredients. 💡
Ingredient Prep
Mince your 1 clove Garlic Clove first and store it in an airtight container with 1 tbsp Lime Juice to prevent browning. Measure all dry ingredients (1 tbsp Granulated Sugar, spices) into small bowls the night before. This cuts active prep time to 5 minutes.
Batch Making
Double or triple the recipe—it keeps well for 1 week refrigerated. I use mason jars for storage, which make it easy to shake and remix before use. Label with the date so you remember when to use it by.
For larger batches, use a blender to ensure perfect smoothness. Process all ingredients except water, then add 2 tbsp Water gradually while blending.
Day-Of Efficiency
If making same-day, prep all ingredients before starting. Have your 0.5 cup Hoisin Sauce and 0.5 cup Peanut Butter at room temperature for easier mixing. The whole process takes 10 minutes from start to finish. ⏰
Flavor Boosting
Let the finished sauce sit at room temperature for 30 minutes before serving. This final rest allows the Sriracha Sauce to distribute evenly and the flavors to reach their peak. I notice the umami deepens significantly during this time.
Nutrition Facts
Frequently Asked Questions
Can I use crunchy peanut butter instead of creamy?
Yes, but it will create a slightly grainy texture. For smooth results, use creamy peanut butter. If crunchy is all you have, blend the sauce briefly to break up the peanuts.
How do I adjust the spice level?
Start with 1 tsp Sriracha and taste. Add more in ¼ tsp increments until you reach your preferred heat. Balance extra spice with a touch more sugar if needed.
What if my sauce is too thick?
Thin it with warm water, 1 tsp at a time, until it reaches your desired consistency. The sauce should coat the back of a spoon but still drizzle easily.
How long will this sauce stay fresh?
Stored in an airtight container in the fridge, it keeps for 1 week. Stir well before each use as ingredients may separate naturally.
