TempPro TP19H Digital Meat Thermometer for Cooking, 1 Sec Instant Read Food Thermometer with Motion-Sensing Wake for BBQ Grill Oil Fry Candy for Fathers Day Gift for Dad Men (Previously ThermoPro)

Instant read temperature probe is de wey. I've had this one a couple years and it works well. https://www.amazon.com/dp/B07XXSYLL8

I don't use a griddle on my grill. With my side-control burner setup it would need to be full length, which would be fine if I wanted one. But this is not a concern for front burner grills. Your setup makes griddling, indirect cooking, and the smoking-with-chips-in-a-foil-pan even easier to manage. My only other outdoor cooker is a Cuisinart 3-in-1 propane pizza oven that came with a griddle insert and grill grate. I use the pizza stone for pizza, and have never used the griddle or grate once <shrug> But if you want to get that griddle, then go for it. $99 for an insert that fits nicely is reasonable as long as it's big enough for what you want to cook and heavy/thick enough to give you the thermal performance you prefer. You can always sell it on FB marketplace for $25 or 50 if it doesn't work for you and try something else. If your Genesis griddle and chamber can hot enough (600F+) you can probably make a decent pizza with it too. Tongs: https://www.amazon.com/Grill-Tongs-Resistant-Stainless-Grilling/dp/B0FKSVTNB5 is more or less what I've had about as long as my youngest kid has been alive. Smashburger spatula (5"x6" variant): https://www.amazon.com/dp/B0C8TJ532J is nice and heavy with a full tang, and beveled edge to get under the thin patties. It's also heavy enough to sit flat and keep tortillas from bubbling, which is a plus. Scrubber: https://www.amazon.com/Cast-Iron-Skillet-Pre-Seasoned-Cookware-Round/dp/B072BX42TN I have one of these for my cast iron pan and use it to clean char off the pans I use when smoking. This would be good for a cast iron or steel griddle too. Gloves: https://www.amazon.com/dp/B0BR7VKYWD and inserts for handling BBQ or other hot things https://www.amazon.com/dp/B07MVWY6XR Probe thermometer: https://www.amazon.com/dp/B07XXSYLL8 Should use up the rest of that savings on the items we skipped :) PS -- one more thing. If you heed my advice and skip the cover, then get a medium-soft brush to shoo the dust away before use. Something like https://www.amazon.com/Rbenxia-Household-Fireplace-Furniture-Woodworking/dp/B0BZ87PH4B But test it on an inconspicuous spot of the lid to make sure it doesn't scratch. Soft horse hair shouldn't but you never know.

Your best bet is to get a meat probe so you'll know what the temp is on the inside before pulling it off the grill. This is the best for the money and it's super cheap right now. https://a.co/d/02HSBjbv

That's where an instant read thermometer like this: https://www.amazon.com/ThermoPro-Thermometer-Grilling-Waterproof-Ambidextrous/dp/B07XXSYLL8?th=1 comes in. Probes won't work well with wings.

Your 185 add and 135 pour are a reasonable start. For the bumpy tops, I would test a slightly warmer pour and track each batch with a TempPro TP19H probe. Hot throw still depends on wick, FO, and cure time too.

Buy your dad a thermometer. They are cheap.
