Step 1

To make a roux, melt butter in a small pot on low heat. Once the butter is melted, add flour and mix well and cook for 3-5 minutes until bubbles start to appear on the surface. Add garam masala, chilli, cumin, turmeric and salt and cook, stirring, on low heat for 3 minutes. Remove from heat and set aside.

Step 2

Heat up a medium pot and add 2 Tbsp oil. Add chopped onion and saute for couple of minutes oruntil translucent. Set aside on a plate.

Step 3

Put the same pot back on the heat and add another 2 Tbsp oil. Cook beef for couple of minutes or until brown, add carrots, potato and onion back to the pot and cook for 5 minutes.

Step 4

Add 1 litre of water to the pot (this should be enough to cover the vegetables and meat), bring to the boil, reduce the heat to medium-high and cook for 15 minutes or longer if you have time. Remove scum as you cook.

Step 5

Add 6 Tbsp (110g) of the roux into the pot and stir to dissolve, thickening the curry.

Step 6

Add the seasoning ingredients and bring backto the boil. Serve with steamed rice.
