Using a flat-bottomed wok on a hot plate, induction cooktop, or ceramic cooking top is practical and can be effective, but it may not be as efficient as using a wok on a gas stove. Here are a few factors to consider:
Heat distribution: Gas stoves provide more direct flame contact to the bottom and sides of the wok, resulting in quick and even heat distribution. On the other hand, flat surfaces like induction or ceramic cooktops distribute heat through electromagnetic fields or radiant heat, which may not be as intense or immediate as a gas flame. This can affect the overall performance of the wok.
Wok stability: Gas stoves typically have wide grates or supports that can securely hold a round-bottomed wok, allowing it to sit in a stable position. With a flat-bottomed wok on a flat surface, stability can be a concern. However, some flat-bottomed woks are designed with a wider, more stable base to address this issue.
Heat retention: Gas flames provide continuous and intense heat, which helps the wok retain heat even when ingredients are added. On induction or ceramic cooktops, the heat may fluctuate when ingredients are added, requiring more time for the cooktop to regain the desired temperature. This can impact the stir-frying or high-heat cooking techniques typically used with a wok.
Cooking surface material: The material of the cooktop can also influence the effectiveness of a wok. Induction cooktops work best with materials that are magnetic, such as cast iron or stainless steel. Flat-bottomed woks made of these materials are more compatible with induction cooktops compared to non-magnetic materials like carbon steel.
Despite these differences, many people successfully use flat-bottomed woks on hot plates, induction cooktops, or ceramic cooking tops. It may take some adjustments to cooking techniques and heat management to achieve similar results as on a gas stove. Preheating the wok, using higher heat settings, and being mindful of heat fluctuations can help improve performance.
If you are a frequent wok user, it may be worth considering a portable gas burner or a dedicated wok burner, as they can provide more traditional and optimal conditions for wok cooking.
