This dip is made up of white vinegar, chillis and rock sea salt. Some people use iodised salt instead of rock sea salt. I prefer the rock sea salt for this because of the texture. Some people also like to add crushed garlic, onions, and/or ground pepper with this type of dip. And, sometimes, I do too. Of course, as always, you can drop the chillis if you're not in to spicy stuff.
I like using this dip for many fried or grilled stuff - like fried fish, dried fish, pork chops and barbecues. Sometimes, I also use it with sardines. Or pork cracklings and prawn crackers.
A sample dish where I used this dip is the Grilled Pork Barbecue on Skewers.
