Vendhaya Kuzhambu

the dark tamarind gravy of Tamil Nadu that takes its name from the fenugreek seed: vendhayam toasted almost black and simmered in sour tamarind and sambar powder, its deliberate bitterness set against sourness, salt, and heat

Origin: Tamil Nadu, South India

From the journey of Fenugreek.

Vendhaya kuzhambu is named for its principal ingredient: vendhayam is the Tamil word for fenugreek seed, and kuzhambu is the general term for the sour, thin, tamarind-based gravies that are the backbone of the Tamil midday meal. It is one of a very small number of dishes anywhere in the world built deliberately around bitterness. The seeds are toasted in oil until they are deep brown, well past the point at which most cooks would take fright, and then simmered in a sharp tamarind extract with sambar powder, garlic, and shallots until the whole gravy is dark, thick, and pungent. The result is a masterclass in the Tamil handling of the six tastes. The bitterness of the toasted fenugreek is not softened or hidden; it is set squarely against the sourness of the tamarind, the salt, the heat of the chilli, and the sweetness of a small piece of jaggery, so that no one taste is allowed to dominate. The kuzhambu is deliberately made thick and strong, and it is eaten in small quantities: a spoonful or two poured over hot rice with a slick of gingelly oil, alongside a dry vegetable poriyal and an appalam. It keeps for several days without refrigeration, improving as it sits, and this keeping quality made it a travelling food and a dish for days when nothing fresh could be had. In many Tamil households it is also regarded as a digestive and a cooling food, and it is cooked for women after childbirth, fenugreek's oldest role of all.

Ingredients

Kuzhambu

2 tbsp whole fenugreek seeds (vendhayam)
4 tbsp gingelly (sesame) oil
1 tsp black mustard seeds
0.25 tsp asafoetida (hing)
12 small shallots (sambar onions), peeled and left whole
8 cloves garlic, peeled and left whole
2 dried red chillies, broken
1 sprig fresh curry leaves
40 g tamarind, a lime-sized ball
500 ml warm water, for the tamarind
2 tbsp sambar powder
0.5 tsp ground turmeric
1.5 tsp fine salt, or to taste
1 tsp jaggery or brown sugar

To Finish

1 tbsp rice flour, slaked in 3 tbsp water (optional, to thicken)

Method

Soak the tamarind in the warm water for 15 minutes, then squeeze it thoroughly with your fingers and strain, discarding the fibres and seeds. Reserve the tamarind extract.
Heat the gingelly oil in a heavy pan over a medium heat. Add the mustard seeds and let them pop, then add the fenugreek seeds and fry, stirring, for 40 to 60 seconds until they turn a deep reddish-brown and smell strongly toasted.
Add the asafoetida, dried chillies, and curry leaves, then the whole shallots and garlic cloves. Fry over a medium heat for 5 to 6 minutes, until the shallots are golden and softened at the edges.
Stir in the sambar powder and turmeric and fry for 30 seconds in the hot oil, then immediately pour in the tamarind extract, standing back as it spits. Add the salt and jaggery.
Bring to a boil, then reduce to a steady simmer and cook, uncovered, for 20 to 25 minutes, until the gravy has darkened, thickened, reduced by about a third, and the oil has risen and pooled on the surface. If it is still thin, stir in the slaked rice flour and cook for 2 minutes more.
Take off the heat and leave to stand for at least 15 minutes before serving. Serve a small ladleful over hot rice with a spoonful of gingelly oil, alongside a dry vegetable poriyal and an appalam.

Notes

The fenugreek should be assertive: this dish is meant to taste bitter, and cooks who reduce the seed to a token half-teaspoon have made a different and lesser kuzhambu. Gingelly (toasted sesame) oil is the correct fat and its flavour is part of the dish; groundnut oil is an acceptable substitute. Vatha kuzhambu, a close relative, adds sun-dried vegetables such as manathakkali or turkey berries. The gravy thickens considerably on standing and may be loosened with hot water. In many Tamil homes it is regarded as a digestive and is cooked for new mothers, fenugreek's oldest and most widespread use.
