Within the grand, yet nebulous universe of what food and culture writers deem as “Asian” cooking and gastronomy, there is a deep love and affinity for the stir-fry. In a hot oily pan, various combinations of vegetables and proteins are tossed and transformed into something wonderful. The simple act of tossing becomes momentous – a way to incorporate flavours and aspects of a cuisine’s eccentricities with chosen ingredients in an endless number of ways. To say that the stir-fry “belongs” to as specific culinary tradition is contentious at times. While the origins of stir-fry, as a cooking technique and dish, originated in China, many cultures across the Asian continent and beyond have embraced it within their own cooking traditions.
Growing up in the Khmer diaspora of the United States, my family and friends have had many conversations about what truly constitutes “Khmer” food and cuisine. More often than not, a joke about Cha (ឆា) would be made. Typically referencing how our moms would throw together whatever vegetables were floating around in our fridges with slices of random meats to feed us on small budgets of both time and money. To spruce up one’s cha, additional clumps of garlic, onion, chili peppers, and or ginger were fried and immediately dashed with soy sauce, fish sauce, and oyster sauce.
These core ingredients, with their strong and savoury aromas, constantly perfumed our kitchens. We ate cha for lunch, for dinner, at family potlucks, and when we were sick — to the surprise of many. Stir-fries as being curative cuisines, or the foods you consume (and lean on) when you’re unwell, is not a common association. In what reality could an oily and heavily spiced dish facilitate healing?
These were just some of my initial thoughts when I began my doctoral research in Siem Reap, Cambodia on Khmer traditional and folk food-medicines used in response to changes brought forth by seasonality, maternity, and the COVID-19 pandemic. Across the interviews and conversations that took place, the consistent mentioning of a number of Khmer dishes which defined my childhood arose, with several types of cha being the most common. As I listened to each study participant’s reflections on food-medicines and/or curative cuisines, the actions and rationalities of my mother began to clarify intensely.
Whenever my sister or I were sick, she’d encourage us to eat chili peppers, limes, black pepper, ginger, and garlic in excess. Her rationality was that I needed to “warm my body” and that these ingredients would do that for me. Alongside bowls of borbor (rice porridge) and snau (soup), she’d prepare us some cha kgneuy (ginger stir-fry). This orientation of rice, soup, and stir-fry embodied the characteristic spread of Khmer cuisine — a little bit of everything: rice, soup, a fresh vegetables and herbs plate, and cha to bring it all together.
In both traditional and folk Khmer medicine, health and wellness are partially reliant on the balancing of bodily humors. Under the humoral theory of medicine, the body is made up of four distinctive humors (blood, phlegm, black/yellow bile) which correspond to specific organs and well as conditions (hotness, coldness, wetness, dryness). When these humors are pushed out of balance for one reason or another, illness ensues. To address this, both traditional and folk Khmer medicine approaches feature consumable remedies that shift one’s humoral orientation back into alignment.
In traditional and folk Khmer food-medicines, cha is a ubiquitous remedy because of its versatility. The ingredients of the cha determine its humoral qualities and impact. You can humorally “cool” or “warm” your body by eating a specific kind of cha. During pregnancy, cha trakhoun with oyster sauce (stir-fried morning glory) or cha mereh (stir-fried bitter melon) is eaten to cool and soothe the humors. In contrast, during postpartum as well as for COVID-19 prevention, cha kgneuy (stir-fried ginger with slices of meat) is used to warm the body and increase immunity.
In combination with other nourishing Khmer dishes, as well as the occasional medicinal decoction, cha dishes act as core components of the traditional and folk Khmer food-medicine healing regiments. In this way, cha blends together processes of eating and healing within certain contexts. The importance of cha to Khmer culture is exceptional, no matter how you frame it. Walk into any restaurant in Cambodia, and you’ll be sure to find one on the menu!
