This salsa was very simple to make and delicious with the lager beer! I like when salsas aren't cold, as the flavors really come through. It was perfect with our cheese and chorizo quesadillas.

can it be any type of beer? how long can u keep it for?

Indeed you can experiment with different types of beer. Just don't go too crazy and use something super dark, but then again, you can do that to, if you like. That's the great thing about cooking you are free to experiment and tweak almost any recipe until it suits your tastes etc. Cheers!

If using Serrano peppers, do you boil them or simply add them in a later step?

You can simmer them along with the tomatoes. This helps to soften them. Cheers!

When adding the beer can it be room temperature or those it need to be cold?

Thanks!

Either cold or room temperature beer would work. Cheers!

I love how simple this is and a great use of all of my tomatoes. I have used a basic lager to wonderful Mexican beer to my husbands home brew.

I made the salsa and it turned out great, except it is a little to spicy. What can I do to make it a little less spicy. Next time of course I will use less chillies, but I still have some of the spicy leftover.

The spiciness is quite dependent on your tastes. It also depends on the peppers, sometimes they are hotter, sometimes they are more mellow. Next time you might just try using fewer chillies.

And if you have some leftovers, you could always make another batch. Only this time and don't use any chillies (or fewer) and combine the two. Cheers!
