In a bowl or pan large enough to fit the salmon, mix the soy sauce, apple cider vinegar, sesame oil, ground ginger, garlic powder, rice vinegar, maple syrup, and sesame seeds
Once mixed, rinse, dry, and toss the salmon in the marinade, coating all sides
Place the container in the fridge and allow the salmon to marinade for 15 minutes
After, heat a frying pan on medium-high heat for 2 minutes
Without coating the pan, remove the salmon from the marinade and place in the heated pan
Sear the salmon on the first side for 2 minutes
Flip the salmon and sear for 1 minute on the second side
After 1 minute, cover the pan and allow the salmon to cook for another minute on that side
Remove the lid and flip the salmon, rolling it around in the juices as you flip it
Reduce the heat to low and cook for another minute
Flip salmon for the last time, remove the pan from heat, and allow to sit in pan for 1 final minute
While the salmon is "cooking" on the side, heat a small sauce pan for 2 minutes on medium heat
Take the remaining sauce marinade and pour it into the heated sauce pan
Take the almond flour and dissolve it into 1/4 cup of water
Add the almond flour slurry to the sauce pan when it has begun to simmer
Mix well and allow the sauce to simmer for 2 minutes
Increase the heat to medium-high and add tahini
Allow to bubble and boil for 2 minutes, stirring occasionally to ensure sauce thickens
Remove sauce from heat and serve over salmon
