Zabaglione vs Tocino de Cielo (Heaven's Bacon Custard)

Both desserts lean on egg yolks and sugar, yet pull them in opposite directions. Zabaglione whisks yolks with sugar and sweet Marsala over a gentle bain-marie until frothy and much larger in volume, ending as a light, airy custard thick enough to coat a spoon, served warm the moment it is ready. Tocino de Cielo instead combines twelve gently whisked yolks with a hot sugar syrup, deliberately avoiding air, then bakes them in a water bath over caramel. Chilled and unmolded, it is dense and silky, its sweetness deepened by amber caramel rather than wine.
