Step‑by‑Step Instructions for Crispy Purple Sweet Potato Cakes
Step 1: Prep Sweet Potato
Begin by cooking your sweet potatoes in a pot of boiling water for 30-40 minutes, or until a fork easily pierces through. Once cooked, drain and let cool slightly before peeling and mashing them into a smooth puree. This step is essential for your Crispy Purple Sweet Potato Cakes, ensuring they achieve that delightful, natural sweetness.
Step 2: Mix Ingredients
In a large mixing bowl, combine the sweet potato puree with glutinous rice flour and brown sugar. Gradually add water, just enough to achieve a cohesive dough that holds together without being overly sticky; it should look smooth and pliable. Stir the mixture well until all the ingredients blend seamlessly, creating the perfect foundation for your cakes.
Step 3: Form Cakes
Once your dough is ready, turn it out onto a clean surface and shape it into small, flat cakes about ½ inch thick. For added texture and flavor, roll each cake in white sesame seeds, ensuring they are evenly coated. Place them on a tray while you heat the skillet, ready to cook your vibrant Crispy Purple Sweet Potato Cakes.
Step 4: Cook Cakes
Heat a non-stick skillet over medium heat and add a touch of oil to prevent sticking. Place your coated cakes in the skillet without overcrowding; do not rush this step. Cook each cake for 3-5 minutes on one side, checking for a lovely golden brown color before flipping them over to cook the other side. A crispy exterior is what we’re aiming for!
Step 5: Season
Once both sides are beautifully golden and crispy, transfer the cakes to a plate lined with paper towels. Before serving, sprinkle them lightly with flaky kosher salt to enhance their flavor. Now your Crispy Purple Sweet Potato Cakes are ready to be enjoyed—pair them with honey or fresh fruit for a delightful treat!
