1a. 12 dried chillies or long red fresh chillies (cayenne pepper) (seeds in) makes a fairly spicy curry but it's not "blow your head off" spicy because the long cook time tempers the spiciness. You can adjust the level of spiciness to your taste - use 6 for a mild curry. To reduce spiciness, you can deseed the chilli - I do not do this.
If using dried chillies, rehydrate in boiling water (use lots, ignore the measly splash I used in the video, that was a mistake).
1b. Onion: Use a brown, white or yellow onion about the size of a tennis ball. Or half a large one or 6 shallots/eschallots chopped
2. To prepare lemongrass, peel the reedy green shell to reveal the softer white part on the bottom half of the lemongrass. Slice the white part and very pale green part only - the green part is too reedy.
If lemongrass is hard to come by, you can use PASTE: 2 tsp in the spice mix and add an extra teaspoon when you add the coconut milk etc. :)
3. Galangal is like ginger but it has a more sour and peppery flavour. If you can't find it, just substitute with more ginger and a grind of black pepper.
4. You can use any slow cooking cut of beef for this recipe. As with all slow cooked beef recipes, the fattier beef, the juicier the meat will be when cooked. I like to use chuck, gravy beef or beef cheeks as I think these cuts have the best balance of fat and fibrous tissue.
It is best to buy one piece and cut it yourself into large cubes about the size of golf balls. Larger cubes are better for this dish because this is not only slow cooked but also cooked down to reduce the sauce to almost a "paste" like consistency and if you use small pieces of beef, they may fall apart and shred in the pot when you stir the curry. It is much easier to handle larger pieces.
5. Smash the lemongrass to help the flavour infuse into the curry. Use the side of your knife, a meat mallet or a tin.
6. Tamarind puree is made from tamarind fruit. It is quite tart, but not as sour as lemon. You can buy tamarind puree from the Asian section of large supermarkets in Australia (or Asian grocery stores). If you are using tamarind pulp (sticky block of dried tamarind), soak it in 2 tbsp of hot water and remove the seeds, then use as per recipe directions.
You can substitute the tamarind with 2 tsp of vinegar (white or brown, but not balsamic) or lemon juice.
7. Kaffir Lime Leaves - there is no substitute for the earthy lime flavour you get from fresh kaffir lime leaves so I really recommend buying fresh ones. They freeze well and last for ages and are commonly found in many South East Asian dishes. You can substitute with dried kaffir lime leaves. As a last resort, you can use 1 tbsp of lime juice + the rind of 1 lime, but the flavour will not be quite the same.
8. To make this in a slow cooker, do the steps up to searing the beef in a pan then pour the contents in your slow cooker. Pour the water into the pan and bring to simmer, making sure to scrape all the brown bits off the bottom of the pan to mix in with the water, then pour the water into the slow cooker (make sure you scrape in as much of the brown bits as you can!). Slow cook on low for 6 hours (or pressure cook on high for 30 minutes). Then pour the curry into a pot and follow the recipe steps to reduce the sauce.
9. This is what happens when the Sauce reduces: Once the sauce reduces right down, the oil will separate (see photo in post). Then you end up browning the beef in that oil - this is where the deep brown Rendang colour comes from. Rendang is not a wet, saucy curry, it all reduces down into a sticky paste that coats the beef.
By this time, the beef should be "fall apart at a touch" and there will be bits of shredded beef that looks like coconut that stick to the beef.
10. Simple Lightly Pickled Cucumber Side that goes with this well: Slice cucumbers on the diagonal and place into a bowl. For each cucumber you are using, sprinkle over 1 tsp of rice wine vinegar, a small pinch of salt and white sugar (each). Leave to lightly pickle for at least 20 minutes, up to 24 hours.
11. STORING: Rendang, like other slow cooked things, just gets better with time. Great on the day it's made, fantastic the next day and the next. Freezes well too.
12. Originally published in November 2014, updated to improve as follows: original recipe used whole cardamon and cloves, these are impossible to pick out and I don't like crunching into them. So I now use powder. Also, in authentic recipes, the curry paste goes in first then the beef is added. Doing it this way, the beef does not brown. I like browning beef first because you get that gorgeous caramelisation that adds flavour.
