Frequently Asked Questions
Q: How long does homemade Thai sweet chili sauce last?
A: When stored properly in an airtight container in the refrigerator, it stays fresh for up to 3 months.
Q: Can I make this sauce less spicy?
A: Yes! Reduce the number of chilies or remove their seeds before processing. You can also use milder peppers like red jalapeños.
Q: Why did my sauce turn out too runny?
A: This usually happens when the sauce isn’t simmered long enough or the cornstarch wasn’t properly activated. Make sure to cook until it coats the back of a spoon.
Q: Can I use regular white sugar instead of palm sugar?
A: While palm sugar provides the most authentic flavor, you can substitute it with brown sugar or white sugar. The taste will be slightly different but still delicious.
Q: Is it normal for the color to vary between batches?
A: Yes! The color can vary depending on the chilies used and how long you cook the sauce. Anything from bright red to deep orange is normal.
