Tweason'ale has little to no hop character, and is fairly heavy on the buckwheat honey. I'd go 80% sorghum extract and 20% buckwheat honey, use only a single bittering hop addition of something very clean, probably magnum or millenium, and then rack onto not a whole lot of strawberries in secondary. You don't want so much strawberry that it turns the beer red, after all; I think the idea is that the sorghum actually has a slight strawberry character on its own (I notice this when drinking Bard's, for instance), and the strawberries should subtly enhance it, not dominate. But use good-quality strawberries; frozen is fine, as long as they're from a good source. Tweason'ale has very light body and negligible head retention, so leave out any steeping grains or maltodextrin additions if you want to duplicate the appearance and mouth-feel.
