Frequently Asked Questions
Can I use salted caramel sauce?
Use a thick caramel that sets when cool; pourable sauce will run off the bars.
Why are pretzels soft?
They absorb moisture from caramel over time; add them shortly before serving for maximum crunch.
Do these bars need refrigeration?
Follow the caramel product label; refrigerate if it contains perishable dairy and serve cool.
