Soak a fistful of tamarind, preferably a year old, in a glass of warm water for three hours.
Strain the tamarind to get a concentrate, where the water consistency is a little thick.
Dry roast and powder a tablespoon each of fenugreek and white sesame seeds and keep aside to cool.
In a large deep pan heat gingelly oil and roast 25 dry chillies. If you want it really spicy, after roasting, crush them and keep them separately. If you want medium spice crush half and keep the rest as it is.
To the heated oil, add the Bengal gram, black gram, mustard seeds, curry leaves and asafoetida. When these have roasted, add the tamarind water. Add a few tablespoons of ground nuts and cashews and allow them to get fried in the oil.
On a low flame let boil and as the oil separates, add the dried powder, chillies, turmeric powder and salt.
Keep stirring till you smell the flavours and the paste thickens.
Pulikaachal can be eaten as a dip, chutney or mixed with hot rice. Don’t refrigerate — it will lose its flavour and consistency.
