Japchae is a Korean dish enjoyed cold as a side dish or served as a hot main course over a steaming bed of rice. A staple found at celebrations and festive holidays, this vibrant dish is made with sweet potato starch glass noodles, featuring a medley of colourful vegetables. Japchae is well-loved as it has a balance of sweet and savoury flavours, blended with crunchy, chewy and soft textures. For a heartier meal, add protein such as thinly sliced egg omelette, strips of meat, or strips of hard tofu for a vegan friendly meal. The secret to getting the balance of this versatile dish right is to be mindful of the different cooking times for each ingredient. Prior to serving, top off the dish with an additional generous helping of roasted sesame seeds. Leftovers can be kept refrigerated and reheated to restore the noodles to its chewy state.
