You can try to wash your bud after decarbing the bud.
I make edibles with AVB instead of fresh bud that’s decarbed, and soaking it in water for 24-72 hours and changing the water every couple of hours has made a noticeable change in the earthy buddy taste.
Any other method like ethanol, strips cannabanoids and terpenes, that’s why the bought edibles taste different, lacking the terpenes and cannabanoids that get stripped when using ethanol. Some add terpenes back in, but it’s not the same. The terpenes and cannabanoids are what gives strains their unique taste/flavor and affects.
If you use ethanol almost all your edibles will give you the same effect, making your own with butter/oil saves the terps and cannabanoids allowing different effects.
Also, ethanol/butane and other methods have a chance of going boom if not done right, plenty of reasons to avoid the chemical extraction methods.
