Hot Sauce Love

That sauce that you dip taco chips to. it’s with vinegar, tomato, onion, chili peppers (green, red), etc.

It’s so delicious. i live in europe so there may not have ingredients that’s available in US.
how long can i store that sauce in the fridge before it get ruined?

also i dont access to jalapeno pepper. can i subtitute it with dried red pepper?

how it will taste if i just use standard onion?
what can use this sauce for aside from tacos chips?

can i pour it on toast bread or sausages?

The spicy Thai fish sauce with chili peppers that you would find at a table at Thai restaurants.

The spicy and sweet Vietnamese fish sauce that is served with deep fried egg rolls at Vietnamese restaurants.

How do I make them?
