Help troubleshooting my first Almond-Lemon Entremet Tartlet — especially the mousse and glaze
Hi everyone! I'm quite new to this, so apologies if some of these problems are obvious. I'm mainly trying to understand what went wrong and how I can improve.
I was making an Almond-Lemon Entremet Tartlet:
pâte sucrée → almond praline ganache → vanilla white chocolate mousse + lemon gel insert → neutral glaze → candied lemon & almond garnish
TL;DR
Pâte sucrée: difficult to work with in my ~32°C kitchen; thin walls/thick base and uneven browning.
Almond praline ganache: worked well.
Lemon gel: worked, but initially far too sour.
White chocolate mousse: complete disaster. It behaved like ice cream, wouldn't unmold and collapsed after thawing.
Glaze: haven't attempted yet.
Looking especially for a proven agar-based mousse that can freeze → unmold → thaw while retaining its shape, and a transparent agar glaze.
- Pâte sucrée
The dough became unworkable very quickly in my ~32°C kitchen. I couldn't transfer the rolled dough into the mold like I see in tutorials and ended up pressing it directly into the mold. This resulted in thin walls and a thick base.
I also started baking at 180°C but reduced it to 160°C because it was cooking too quickly. Even at 160°C, the top edges browned before the base developed much colour, so I had to remove it earlier than intended.
I also made it without almond flour.
Recipe
75 g butter
50 g icing sugar
30 g beaten egg
150 g maida
Vanilla
I used a hand mixer for the butter + sugar and egg, then incorporated the flour by hand.
I'd appreciate advice on working with pâte sucrée in a hot kitchen and getting more even baking.
- Almond praline ganache
This was the component that went most according to plan.
Almond praline paste
70 g almonds
40 g sugar
12 g water
1 small pinch salt
Ganache
75 g almond praline paste
45 g white chocolate compound
65 g Amul Fresh Cream
1 small pinch salt
The praline took quite a while because my grinder struggled, and the almonds released quite a lot of oil, but otherwise this component was good.
- Lemon broken-gel insert
This worked structurally as expected, although it was initially far too sour, so I had to adjust by making the same gel without lemon to dilute it
Recipe
50 g lemon juice
35 g water
20 g sugar
1 g agar agar
I mixed the agar with the sugar, added the liquids, brought it to a proper boil and continued boiling for about 60 seconds while whisking. After setting, I blended it into a smooth gel for the insert.
This component is fine now.
- White chocolate vanilla mousse — the disaster
This is where things really went wrong.
I wanted the mousse deliberately less sweet, so I reduced the white chocolate. I also had to use agar because I cannot use gelatin.
Recipe I used
120 g whole milk
120 g white chocolate compound
190 g 35% whipping cream
1.5 g agar agar
1 tsp vanilla essence
I infused the vanilla in the milk, then added the agar.
The problem was that the agar mixture started setting before I could properly incorporate the whipped cream. I reheated it and broke the gel back down with a hand mixer, then folded in the whipped cream and filled the sphere molds with the lemon insert.
I froze them for around 12 hours.
Even after freezing, the mousse wasn't nearly as firm as I expected and wouldn't demold properly. After thawing in the refrigerator it essentially turned into a soft, ice-cream-like blob and completely lost the spherical shape.
In hindsight, reducing the white chocolate may have been a mistake because it wasn't just contributing sweetness — it was also contributing structure.
I'm particularly looking for advice on:
white chocolate + vanilla + whipped cream + agar → freeze → unmold → glaze → thaw while retaining shape.
I don't mind a different mouthfeel from gelatin mousse. I just need the sphere to actually survive thawing.
- Neutral glaze
I haven't attempted this yet because the mousse sphere was a disaster.
I can only use agar agar. I don't have Pectin NH, and I'm okay with somewhat less gloss or a different mouthfeel.
What I need is a transparent/neutral glaze suitable for a frozen mousse sphere.
I'd particularly appreciate an actual tested agar-based recipe, rather than simply replacing gelatin with an assumed amount of agar.
- Candied lemon & almond
These are done and turned out fine.
Unfortunately, they currently have no mousse sphere to garnish.
Any help is appreciated, but especially advice or proven recipes for the agar-based mousse and transparent agar glaze. I'd really like to avoid making another experimental batch after this one!
