1 pkg. Russian mustard mix (100 g.)
3/4 c. hot water or pickle juice (not boiling)
1 1/2 tbsp. sugar
1 tsp. salt (omit if using pickle juice)
1 tbsp. olive oil
pinch powdered cloves
pinch nutmeg

I can't read the recipe on the pouch, so here's the English translation. Adjust measurements if mix is more or less than 100 grams.

Blend mustard mix, water, sugar and salt into thin paste. Blend in oil and spices. Let sit overnight before refrigerating.
