Hey JohnT you bet! I really like HOT salsa, but it would kill my in-laws, so I make a mix.
Here is a favourite of mine:
http://www.simplyrecipes.com/recipes/canned_tomato_salsa/
I sub out the peppers for a mix of mild-extremely hot ones - as long as it's the equivalent amount you're ok to do that
I also enjoy this one, it's for a small batch and again, I sub out the peppers into mild-hot heat depending on my audience. Also, you can chop the stuff instead of food process if you like a chunkier consistency. I use a food processor for nearly all of my salsa these days.
Beyond hot
8 plum tomatoes
1 large onion
4 lg cloves garlic
4-5 jalapenos
2 small hot chili peppers
1/4 c cider vinegar
2t dried cilantro
1t each pickling salt & sugar
Process till almost smooth in blender or processor
Put in pot, add vinegar, cilantro, salt & sugar bring to a boil over high heat, reduce heat & boil gently for 15 min or until thickened.
Ladle into jars, with 1/2 inch space. Process for 20 min for 250ml jars, or 500 ml jars. Makes 750 ml.
Finally, for something AMAZING that has nothing to do with tomatoes:
Apricot-Habanero Salsa
1 c white vinegar
12 c chopped pitted apricots
2 1/2 c chopped red onion
2 habanero peppers, seeded and chopped
2 red bell peppers, seeded and chopped
1 c loosely packed finely chopped fresh cilantro
1/4 cup honey
2 cloves of minced garlic
1 Tbsp ground cumin
1 tsp cayenne pepper
Plonk everything into a bot and bring to a boil. Simmer for 10 minutes or until thickened. Pour into pint jars with 1/2 inch headspace and boiling water can for 15 minutes. This is also nice with a hit of lime zest/juice.
Will make approximately 8 pint jars.
Enjoy!! I like to make a nice selection depending on what I've got available and who I'm making it for (like my wine, I give 90% of it away). I have a girlfriend who makes stuff out of purple tomatoes and only sweet peppers, or tomatillos and we swap a few jars of each. Makes for a yummy winter.
