I recently had a question from a student attending one of my cookery classes: “What is the difference between light and dark soya sauce?” He had always thought that dark soya sauce is the real McCoy and the light soya sauce is the diet version, like coke and diet coke. I found that misconception fascinating, so let’s talk about sauces, condiments and the five taste senses.
The five basic taste senses
The first four taste senses of sweet, sour, salty and bitter is a more straight forward concept and these tastes can be gotten from ingredients like sugar, honey, citrus, vinegar, salt, coffee etc. Interestingly, spicy is not a taste, it is actually a pain signal, a sensation rather than a taste.
The fifth taste sense is a little more complex. Known as ‘savoury’, this fifth taste sense was discovered by a Japanese researcher around 1910, thus the word ‘umami’ (which means savoury in Japanese) is often used to refer to this fifth taste sense. I would describe ‘savoury’ as a depth of flavour that can be gotten from protein rich food and fermented products like soya sauce, fish sauce, oyster sauce, bean paste, chilli paste etc. Or sea products like seaweed - kombu, nori, wakame and dried bonito etc. Mushrooms are rich in umami too, the most common Asian mushroom packed with deep flavours being the shitake mushroom.
I have picked a few of my personal favourite sauces and condiments to share with you. So, amp up your cooking by using these simple products to bring more flavour to your food.
CHINESE
Light soya sauce
Made from fermented soya beans, a little dash adds umami to both Asian and Western dishes. You can use it as a marinate, for stir-frying, steaming, braising or in dipping sauces. When a recipe asks for soya sauce, assume it means light soya sauce. The term light merely describes the golden brown colour, it is actually more salty than dark soya sauce.
Light soya sauce is used for seasoning and adding flavour and dark soya sauce is used for flavour and adding colour to dishes.
Dark soya sauce
Dark soy sauce is aged longer than light soy sauce and is often mixed with molasses or caramel. It is much darker, sweeter and thicker and less salty than light soy sauce. Normally added to give a depth of flavour, a little sweetness and to provide an appetising glaze to the finished dish. Brilliant for braised or stewed dishes and used in noodles and rice to give them a nice deep glossy finish.
Oyster sauce
Oyster sauce is made from oyster extracts. It has a pronounced umami flavour with a tinge of sweetness and saltiness. Best known for bringing out the savoury taste of other foods, the most common uses for oyster sauce includes stir-frying, glazes, marinades and dips.
Lee Kum Kee is my preferred brand for oyster sauce, for its quality. The founder Lee Kum Sheung had invented this delicious sauce by accident, he had left a pot of oyster soup simmering away at his food stall one day, got distracted and the soup was reduced to a thick brown paste full of savoury flavours with caramelised quality. Not wanting to waste a good pot of oysters, he started selling it to his customers as a rice seasoning. Well, the success is history.
Rice vinegar
When an Asian recipe calls for vinegar, it normally asks for rice vinegar. Don’t panic if you don’t have rice vinegar at hand. Asia grows a lot of rice, so rice vinegar is produced and readily available, just like cider vinegar in UK as we have an abundance of apple orchards, or wine vinegar from the grapevines in Europe, or coconut vinegar from the Philippines.
Simply substitute white rice vinegar with any clear or light coloured vinegars that are not flavoured. Word of caution - if you are replacing with distilled vinegar, reduce the quantity stated, as distilled vinegar is stronger and tastes more acidic.
I find balsamic vinegar a fair substitute for dark rice vinegar although it does not have the toastie rice undertone. Balsamic has a fruity grape background, so water it down with a teaspoonful of water if it is too sweet or syrupy.
Chinese rice wine
Shaoxing wine has a clear, yellow-amber colour with an average alcohol content of 14%. Made of fermented rice and glutinous rice, it is an essential ingredient for preparing meat or fish in Chinese cooking. You can use dry sherry instead for similar aromas. Add it right at the end of cooking directly onto the edge of a hot wok or frying pan.
Just like Champagne can only be produced in the region of Champagne in France, Shaoxing wine must be produced in the Zhejiang province of Shaoxing in Eastern China. Inland, a lower grade of Shaoxing wine is sold for cooking, salt is added to the wine to avoid alcohol tax.
An aged Shaoxing wine can also be consumed as a beverage, served warm to accompany a meal.
Sesame oil
Extracted from sesame seeds, the distinctive nutty flavour and aroma from this delicate oil will transform any dish, be it in cold appetisers, marinades, dips, dressings or dumpling fillings. When used in a cooked dish, it is important to remember to add it at the end of the cooking process, almost at the time when the fire is turned off, to capture its pure essence.The darker coloured toasted sesame oil has a richer flavour compared to the lighter coloured sesame oil. Be aware that most sesame oil comes blended with another carrier oil. For a pure flavour and aroma look out for ‘Pure Sesame Oil’.
KOREAN
Gochujang
A Korean fermented red chilli paste made from dried red chillies flakes called gochugaru, fermented soybeans and thickened to a thick paste with glutinous rice. It has a gorgeous, bold crimson colour, deeply savoury, slightly smoky, with a gentle sweetness from its fermentation process.
In my October Korean cookery class, we will be using gochujang to make the glaze for KFC - Korean Fried Chicken.
VEGAN AND GLUTEN FREE
Hoisin sauce
Translated directly in the Cantonese dialect, Hoisin means ‘seafood’, however it does not contain any seafood products and is naturally vegan.
Gluten free hoisin sauces are available from Lee Kum Kee.
Mushroom sauce
Produced by Lee Kum Kee, their mushroom vegetarian stir fry sauce was designed to be used as an alternative to oyster sauce for vegetarians and vegans. Dishes cooked with the mushroom sauce has similar texture and appearance to those cooked with oyster sauce. It is also very popular to serve a dollop of oyster sauce as a dip.
This mushroom sauce is gluten free. You can also get gluten free oyster sauce by Lee Kum Kee.
Soya sauce
All soya sauce is naturally vegan. Kikkoman makes a lovely rich Tamari gluten free soya sauce. Lee Kum Kee also produce a gluten free soya sauce.
I hope that this week’s column has thrown some light on a few basic Asian sauces and condiments and have inspired you to start building an authentic pantry. I promise that it will unlock a whole new world of taste.
