In the same pan you fried your chicken add a bit more oil without cleaning it out. If you chicken charred too much or there is too much burnt residue clean the pan well before continuing or your soup will taste butter and burnt.
To your oil add your minced ginger and garlic and sautee for about a minute on medium high heat. Watch so your garlic does not burn .
Add your Thai red curry paste and sautee stirring frequently for about 3 minutes. Follow with any leftover marinade and sautee for an additional 2 minutes.
Add your sambal and follow immediately with your stock/broth without salt and water.
Season your soup with fish sauce and add your can of coconut milk.
Heat up on a low simmer for at least 10 minutes, taste and adjust seasoning Add fish sauce for saltiness and flavour, salt to adjust seasoning without adding more fish sauce, sambal for heat and more, red Thai curry paste if you want a richer broth.
Serve this broth over cooked rice noodles, with your sliced chicken, cilantro a lime wedge, soft boiled egg, bird's eye chili, or to taste (they are very hot), and julienned quick pickled carrots.
