This is an entirely inspired dish that you are unlikely to find in any Filipino cookbook. That's because it's a simple side-dish that is unlikely to make it into cookbooks which tend to feature fancier stuff.
It follows the most primitive principles of food. Use fresh ingredients, and touch them up minimally.
The ingredients are simplicity themselves - white radish (daikon), tomatoes, ginger, patis (fish sauce) and vinegar, along with dried anchovies (dilis.)
Served with warm rice, it's the perfect comfort food, and yet texturally complex and nutritionally complete.
4-6 tbsp vinegar (to taste)
2 tbsp patis
4 green chillies (minced)
2 tbsp minced ginger
1/2 cup dried anchovies
salt to taste
Cut the radish into paper-thin slices. A mandoline will help here.
Dice the tomatoes roughly.
Mix all the ingredients together except the anchovies.
Mix in the anchovies right before serving (so that they remain crisp and don't turn soggy.)
