Yeah the top wasn't actually particularly thick at all, I thought it was a nice contrast and compliment to the orange cream without being overpowering. It's just that it was a mess to try to make clean slices through without having it crack in all random patterns. However it was my first time bruléeing something (and first time eating something bruléed actually, I don't recall ever having crème brulée before), so maybe that's just inevitable? Perhaps that's why you only see it used when the product is in a mold, e.g. crème brulée, and not on top of other things like cakes or pies.
A passion fruit cream or curd tart sounds wonderful. The Wayne Gisslen baking textbook also has a variation for raspberry-passion fruit crème brulée, which I'd love to try. I don't think I've ever actually tasted passion fruit before either, but it's a flavour I'd really like to bake with. Kinda hard to find though, from a quick google research it seems passion fruit concentrate/pulp/purée aren't super common products here.
The top is always going to shatter when you cut into it. But you definitely don’t want a really thick top. When it’s too thick The bite is unpleasant. You want it to shatter nicely when you chew it, that light crunchy bite.
maybe make a little individual tartlets. That way you don’t have to worry about cutting into it to serve it
yes passion fruit is difficult to find. We’re very fortunate here in the Napa Valley that we have a company that makes the most extraordinary puréed concentrates for the food industry. They sell directly to the public by mail order. But fortunately there’s two independent grocery stores in town that carry a small selection of their purées. They’re not cheap. But they’re worth the splurge for me when I want to make a special treat But they’re worth the splurge for me when I want to make a special treat. If you have a Mexican grocery store near you check their frozen food section for passion fruit purée.
A couple of the grocery stores in town also carry the fresh passion fruit in season as well. But I prefer the purée concentrate. I use Pierre Herme lemon cream method for the passion fruit. Then use the filling for tarts, cakes, eclairs, and puffs.
The passion fruit is tangy. Somewhat citrusy. It’s very bright. It’s amazing. It’s really my favorite fruit to use for a filling. I make a elderflower lemon chiffon cake Add the passion fruit Cream filling. I ice it with a mascarpone Chantilly whipped cream icing that I stabilize with gelatin sheets. And then I decorate it with fresh berries. That is my signature cake. I developed the recipe for my sister several years ago. She’s crazy about this cake that a grocery store chain makes that is similar to that. I thought I can make a cake like that but better.
