Remember that redosing psilocybin strongly diminishes the effects, so if you start by eating say 1/8th of the total mass in that baggie, then you eat another 1/2 of the baggie, you may only be experiencing doubled effects from your initial dosage. With psilocybin and LSD, it's important to dose all at once for the most part. I would try that small mushroom and maybe another few pinches of the broken up "shake".
I personally always smoke weed on psychs, if you're used to cannabis it shouldn't be a problem. The tramadol may slightly potentiate the high, but I doubt it'd be by very much.
As far as consumption methods go, tea is a pain in the ass to make because if it gets too hot, it degrades the psilocybin greatly. I personally just eat them straight, but the earthy/grassy taste is something that some people find disgusting. I enjoy it though, tbh. I always recommend The Psilocybin Chef Cookbook by K. Mandrake and Virginia Haze though, it's got ton of recipes ranging from savory to sweet and everything in between, as well as a variety of extraction methods using ethanol, milk, etc.
