i don't put shrimp paste in mine but i make it with fish sauce i can give u the way i make it. i love sour mangos.
this is the liquid sauce:
man i don't know my measurements, but here goes:
using a small bowl for sauce, put in about 1/4 of the bowl the fish sauce
about 3 spoons of sugar
about 1 & 1/2 of ground dried red pepper
1/4 spoon of msg [you don't really need it]
1 spoon of ground rice that has been burned so it's brownish [kao kore]
mix it all together and stir, you're get a thick sauce, but if you prefer watery, add more fish sauce, or fix it to your liking.
this way is sorta like the thai nam plah warn. and i prefer it refrigerated.
i don't have a pix of just the sauce but i took a pix of my sour berries in the sauce, the reason why it's dark is because of the kao kore, u don't need to put it in if you don't want your sauce to be dark, it's just the fish sauce and sugar and hot pepper
okay I think I know what you are talking about.
first put 3 spoons of sugar
ground fresh peppers (as many as you like) with the sugar
add fish sauce till all the sugar and pepper is soaked a
add half a table spoon of shrimp paste
