JonG, I hope you'll be happy with a booklet of Domino's vouchers or a home Mozzarella cheese kit.
Either that or if you are as fortunate as expected, and your wife likes pizza, you better get real good at it quite quickly. Of course it's a slippery slope because you'll soon need a good quality (expensive) stand mixer.
In all seriousness, I do hope you receive the gift of home made pizza. Nearly as good as home made fish 'n' chips, for which you'll require a good deep fryer.
To address efficiency though, the thermal load of heating anything to cook a pizza in 90 seconds is going to be questionable unless you cook a few at a time. If I had the stone mason oven on my back deck I could imagine it being quite a talking point but essentially redundant. Firewood fit for purpose is a pricey energy source these days. We need to ask Greta how her pizza is cooked. Maybe big glass lenses and the refractory and reflective properties of hard ice.
Yes Phil. I know. We do not tolerate the drink.
