HAWKINS Futura Hard Anodised Pressure Cooker, 5 L, Black
This pressure cooker is perfection. The lid is the only annoying bit, but it looks so darned good in my kitchen that I can't really complain.
The bottom is heavy duty. This means that when I cook something in there, it's not going to burn to the bottom in this horrible glue-like layer of burning and horrible that happens in cheaper pressure cookers. Also, because it's got such a heavy pot situation going on throughout the pot, it holds heat very well, and gets hot good and quickly. When I make split peas, or other sticking-prone things in here, I have absolutely no problems at all.
When making brown rice, split peas, or other things that tend to foam up a lot: fill the cooker no more than half full (including water!). If you think that 7 litres is too big for you, consider this: the lid needs a bit of wiggle room to get in and out. You're not going to be able to fill it more than 1/2 the way full (INCLUDING WATER) when it's a foamy thing (like beans, or rice; which means that when making those things, the total volume cannot exceed 3.5 litres, which isn't really that much, because 500 grams of beans needs around 1 1/2 litres of water, so when you add that volume along with the volume of the beans, you're working with a razor-thin margin here).
Furthermore, if you're a single person, like me, you can cook more than one thing at a time. Go to the Chinese store, Indian store, or Dollar store and pick up those cheap stainless steel bowls that will fit into your cooker. Throw the included trivet down onto the bottom. Then, add your long-cooking ingredient (like beans), and your shorter cooking ingredient (like rice) into the bowl. Add water for the rice, add water for the beans, slam the lid on, and let it all cook at once. Top to tail, you'll spend like 20 minutes or so to get the thing up to pressure, cooked, and quick-cooled. While the pressure cooker is going, you just sautee off some spices, garlic, onions, whatever, and have it ready for your food. Dinner in 20 minutes, and you didn't have to use tinned beans.
I do use this for small quantities, and it works just fine. I use it for large quantities, and it works just fine. The point is that this pressure cooker is the best I've used in my life, even amongst Hawkins pressure cookers. My mother always owned Hawkins or Presto. I've used this model on both gas and electric with excellent results. The others can't quite make that same claim. This is worth every penny.
