Chop up 2 cloves of garlic and put them into a pestle and mortar with a little salt, then mash into a paste. Add in 1 tsp of palm sugar and 4 cherry tomatoes cut in half to the pestle and mortar, then add 5 green beans cut into 1 inch pieces. Pound these ingredients a little to release the juices. Add 2 tbsp dried shrimp, 2 tbsp fish sauce and 1 chopped Thai birds eye chili and pound again.
