Muthira Thoran
Horse gram with coconut — the highest-protein pulse in the pantry

Plan ahead: plus 10–12 hours soaking and 25 minutes pressure-cooking — required.
The re-engineeringCoconut down to 80 g from about 150 g, oil to 8 g. Nothing else needed doing, because muthira was never a rich dish — it was the pulse of the poorest households and the working cattle, and its rehabilitation as an expensive health food is recent.
Muthira — horse gram, Macrotyloma uniflorum — carries 21.7 g of protein and only 0.62 g of fat per 100 g dry, which makes it the leanest and one of the most protein-dense pulses in the Kerala pantry. It is also the hardest bean here, needing an overnight soak and twenty-five minutes under pressure, and it has a distinctly earthy, faintly bitter flavour that coconut and green chilli are exactly the right partners for. It was fed to animals and to people who had no choice, and it is now sold in Kerala at a premium. That inversion is worth noticing.
Before you start: Start the soak the night before. Twelve hours is not optional for muthira, and a four-hour soak will leave you with a bean that never softens.

Active 15 minutes Total 30 minutes
Scale
4 servings
Ingredients — tap to tick off
- ✓180 g (1 cup) muthira (horse gram), soaked 10–12 hours in plenty of water
- ✓2 g (⅓ tsp) ground turmeric, for the cooking water
- ✓80 g (about ¾ cup) fresh grated coconut
- ✓60 g (about 6) shallots, roughly chopped
- ✓15 g (about 3) green chillies, chopped
- ✓8 g (1½ tsp) coconut oil
- ✓3 g (½ tsp) mustard seed
- ✓2 dried red chillies, broken
- ✓20 fresh curry leaves
- ✓2.5 g (½ tsp) 70:30 salt (M07)
Allergens: Mustard.
Equipment: Pressure cooker — genuinely necessary here; 26 cm pan; flat wooden turner. Substitute: an open pot takes 1½–2 hours and needs topping up with hot water. This is the one recipe in the chapter where a pressure cooker changes what is practical.

Method — tap a step to mark it done, tap a time to start a timer
- Drain the soaked horse gram, discard the water, and pressure-cook in 550 ml fresh water with the turmeric for at full pressure. Release naturally. In a pot, 1½–, topping up with boiling water as needed.
- Test and drain. A cooked muthira should be tender enough to crush between finger and thumb but will still feel firmer than a cooked cowpea — that is correct, not undercooked. If it squeaks against the teeth, give it 5 more minutes under pressure. Drain thoroughly and keep the cooking water; see the leftovers note.
- Crush the coconut, shallots and green chilli together coarsely, keeping it flaky and separate.
- Heat the oil over medium-high, add the mustard seed and wait until it pops and subsides, 30–45 seconds. Add the dried chilli and curry leaves and let them crackle 10 seconds.
- Add the coconut mixture and cook , until the coconut smells nutty and has gone ivory.
- Fold in the horse gram and the salt, lifting from the base with the wooden turner, until coated and hot through, . Taste: muthira takes a little more chilli than cowpea does, because its earthiness needs the lift.
Why this worksHorse gram's seed coat is exceptionally hard and its cotyledons dense, which is why the long soak and long cook are unavoidable — water has to penetrate the coat before heat can gelatinise the starch inside. That same density is why it stays intact in the pan and why it is satisfying out of proportion to its 260 kcal. At 0.62 g of fat per 100 g it is also the only pulse here where essentially all the fat in the panel is coconut you added.
Sourcing note
Horse gram is sold as muthira, kollu, kulthi, hurali or horse gram by every South Indian grocer and increasingly by health-food shops at three times the price. Buy from the grocer. Check the date if you can: horse gram that has been in a warehouse for two years will not soften in any amount of time, and this is the pulse where that failure is most common. There is no acceptable tinned version.
If you are watching…
Blood sugar: 30 g of net carbohydrate at a category glycaemic index near 34 gives an estimated glycaemic load around 10. Note honestly that no Kerala-specific glycaemic index measurement for muthira exists in this book's sources; the category figure is what is available.
Blood pressure: 220 mg per serving from 2.5 g of salt.
Cholesterol: 9 g of saturated fat, all coconut. Cut to 50 g of coconut for about 6 g. A systematic review of horse gram's traditional uses and composition exists (Oli et al., 2024), and it should not be read as evidence of any therapeutic effect; this book makes no such claim.
Swap it
Vanpayar → see R053. Faster, softer, sweeter, 4 g more fibre per serving and 1 g less protein.
Sprouted muthira → soak 12 hours, then sprout 24 hours before cooking; the cooking time falls to 12–15 minutes under pressure and the flavour sweetens noticeably. Follow the food-safety method in R062.
Add 200 g of grated carrot or shredded cabbage at step 5 → six servings, more volume.
Add 100 g of green mango, diced, at step 6 → the sharp Malabar version, and very good.
Make ahead · store · freeze
Given the soak and the cook, this pulse should only ever be made in quantity. Fridge 4 days cooked and drained. Freeze 3 months in 100 g portions — the single highest-value thing in this chapter to have in a freezer. Reheat the finished thoran in a dry pan, 2–3 minutes.
Leftovers
The cooking water — muthira vellam — is drunk warm in parts of Kerala and Tamil Nadu, and it is a pleasant, faintly nutty broth; treat it as a cultural practice rather than a health measure, because there is no clinical evidence about it. Cold thoran folds into R062, into an omelette, or into leftover rice.
Troubleshooting
Never softens: old pulses, or a soak under 10 hours. Both are common with horse gram and neither is fixable once cooking has started.
Bitter or harsh: the soaking water was not discarded. Always change it.
Dish tastes flat: under-chillied. Muthira needs more heat than the other pulses to lift its earthiness.
