Step‑by‑Step Instructions for Thai Stir-Fried Chilli Crab
Step 1: Heat Oil
Begin by pouring a generous amount of vegetable oil into a large, heavy-bottomed pan. Set the heat to medium and wait until the oil shimmers, which usually takes about 2 minutes. This hot oil will create the perfect base for your Thai Stir-Fried Chilli Crab, ensuring a quick and even cook for the garlic.
Step 2: Cook Garlic
Once the oil is shimmering, add the chopped garlic to the pan. Stir-fry the garlic for about 1 minute until it turns a golden yellow, releasing its aromatic fragrance. Be mindful not to overcook it, as you want to avoid bitterness. This step builds a rich flavor foundation for your dish.
Step 3: Incorporate Chilli Paste
Next, stir in the Thai chilli paste, known as Nam Prik Pao. Cook this mixture for another minute, allowing the paste to meld with the garlic and release its spicy, fragrant aroma. The vibrant colors should brighten in your pan, setting the stage for the flavorful addition of crab.
Step 4: Add Crab
Gently fold in the fresh blue swimmer crab, taking care not to break the delicate meat. Stir-fry the mixture for approximately 5 minutes. You’ll know it’s ready when the crab turns a bright orange color, indicating that it’s cooked through and absorbing all the delightful flavors from the chilli paste.
Step 5: Season
Pour in the fish sauce and sprinkle in the sugar, tossing everything together to harmonize the flavors for about 1 minute. The fish sauce will add a deep umami taste while the sugar balances the spiciness of the dish. Taste and adjust the seasoning if desired for a perfectly balanced Thai Stir-Fried Chilli Crab.
Step 6: Finish with Spring Onions
Once the crab is well-coated with the flavors, add the chopped spring onions. Stir quickly to combine, then remove the pan from the heat. The spring onions will add a fresh crunch and vibrant color, elevating this dish as a delightful centerpiece for your table.
Step 7: Serve
Transfer your vibrant Thai Stir-Fried Chilli Crab to a serving plate, using a spatula to showcase the beautiful colors and textures. Garnish with slices of fresh chili for an extra kick and a visual pop. This dish is now ready to impress your family or guests with its enticing aroma and inviting presentation.
