Spices

Curries might have a primary ingredient of meat, seafood, lentils, vegetables or even fruit, but surely what defines this style of cooking in the eyes of many is the combination of spices.

For those just getting into curry-making, know that you're going to have to buy many spices. Of course, you should only buy spices as you encounter recipes that ask for those specific spices. Buy small packets until you know what spices you like and what spices you most frequently use. For instance, I go through large amounts of both coriander seeds and cumin seeds. It makes sense for me to buy large bags of them. Conversely, I rarely use nigella, so I only have a small packet sitting in the cupboard. Large packets are cheaper, yes, but spices don't have an unlimited shelf life. They lose flavour and pungency over time. It's no good saving a few cents on a bag of spice if, by the time you get around to finishing it, it has long since lost its potency.

I buy most of my spices at an Indian grocer. What I can't get there I'll get at either an oriental grocer, a Middle Eastern grocer or an Ethiopian grocer. The latter I've only had to use for some really obscure spices. I don't call for these in my recipes, though, so don't worry too much if you don't have the faintest idea where the nearest Ethiopian grocer is. Incidentally, if you live in Melbourne, you can find a number of Ethiopian grocers in Footscray. An increasing number of Ethiopian and Sudanese grocers are opening in the south eastern suburbs, too. But I digress. I've found Indian grocers to have the best place to shop. Their prices are usually reasonable and their turnover is high. Classy food stores like The Essential Ingredient and Simon Johnson also stock a good range of spices, although expect to may significantly more than you would at the local South Asian place.

Always buy your spices whole. Chilli powder is okay, but about everything else--from pepper to cardamom to cumin--should be bought whole. Sure, with pre-ground spices you save a little bit of time, but the flavour and aroma is inferior. Too, whole spices have a longer shelf life. They're also easier to identify by sight. This is especially relevant in my pantry where a good half of my spice collection is unlabelled.

To maximise the flavour and aroma of spices, you should roast them before grinding them. To do this, heat a small, non-stick fry pan over a low flame. Don't use any oil or ghee. Add the whole spices. Stir with a wooden spoon to prevent them from burning. You'll know the spices are roasted when a strong and pleasant aroma fills your kitchen. Working with spices is all about using your senses.

Many recipes that use curry powder--not a spice in itself, but a blend of spices--often call for you to roast curry powder. If they don't ask you to do it, do it anyway. If the recipe calls for you to fry up some onions, add the curry powder just as the onions begin to soften and roast for a few minutes before adding the next ingredient. If you're supposed to add the curry powder to a liquid, you can roast it on its own in a small fry pan.

To grind spices, use either a mortar and pestle or an electric spice grinder. I use the former. If a recipe calls for you to grind fresh garlic, ginger or chillies, add a little coarse sea salt to the mortar (the bowl). The salt acts as an abrasive, making your job significantly easier. Too, if a recipe calls for many spices to blended together, grind them all in one go. They'll combine as you grind.

When using a mortar and pestle, there's absolutely no need to be forceful. With a granite mortar and pestle like the one I use, the pestle is quite heavy. If you're too forceful, light, round spices such as peppercorns and coriander seeds are liable to bounce out of the mortar and make a mess.

Get to know the properties of the spices in your collection. Try and reach a point where you can recognise them by sight and smell and taste. A good reference book is Ian Hemphill's Spice Notes and Recipes--it's very extensive, although I have a few spices that aren't mentioned in it. Some curry books feature decent appendices on spices. But book or no book, you should learn the properties of spices for yourself. Some spices have a strong flavour or aroma and could, if used carelessly, overpower everything else in your dish. Others you can be more generous with. Understand that not all spices are hot. Some are used to add colour to a dish. Some are sweet. Some are sour. In Indian cuisine, different curries employ different combinations of spices. Some curries are hot. Some curries are sour.

Remember that dried spices often taste different to the fresh ingredients from which they are derived. Dried chilli has a different flavour to fresh chilli. Dried garlic tastes different to fresh garlic. Dried ginger is quite distinct from fresh ginger. If you substitute the fresh for the dry or the other way round, expect a different end result.

How you store your spices is very important. Mistreat your spices and they will lose pungency and flavour. Keep them somewhere cool, dry and dark. Store them in jars or tins or thick zip-lock bags. Some South Asian grocers already sell them in the latter.
