Poking holes in steak: before you marinate your steak feel free to poke some holes it it on both sides using a fork. This helps the marinade penetrate the steak while marinating.
Before Grilling: Wipe off excess marinade before grilling (especially over direct heat) as it will most likely cause flare-ups. Some flare-ups are fine (and we all like a little char!), but we recommend having a spray bottle of water on hand to help calm the flames in case of flare-ups. You can also move your steak over to indirect heat after the initial sear if you have having lots of issues. See: How to Grill the Perfect Steak for more info!
Freezing: You can definitely freeze your steak in the marinade if you want to prep beforehand. Simply place steak + marinade in a freezer-safe silicone bag. Ensure steak is coated in the marinade and then push out as much air as possible while sealing the bag. Store in the freezer for up to 3 months. To thaw, simply place in the refrigerator overnight.
Paleo/Whole30: to make Paleo/Whole30 simply use a compliant ketchup and use coconut aminos instead of soy sauce.
