From the page: The Tetra Pak gives much more than it seems
Idea 9
Pastry scraper and spatula
In artisan pastry kitchens, spatulas have always been precision tools: spreading ganache, smoothing frosting, lifting delicate cookies. Tetra Pak has a layer of plastic and aluminum between the paper, which makes it flexible, grease-resistant and easy to clean — perfect for imitating a steel spatula.
What you need
- 2 to 4 clean, dry Tetra Pak cartons
- Scissors with fine tips
- Ruler or measuring tape
- Pen for marking
- Fine sandpaper or the edge of the scissors to round corners
How to make it
-
1
Wash the cartons well inside, unfold them and let them dry completely — any moisture compromises hygiene and a clean cut.
-
2
With the ruler and pen, mark a rectangle of about 20 x 6 cm for the scraper, and another of 15 x 4 cm with a slightly angled tip for the spatula.
-
3
Cut along the marks with the scissors — cutting in a continuous stroke avoids burrs that would scratch the cake's frosting.
-
4
Round all the corners and run the fine sandpaper over the edges, because sharp corners or loose edges can mark the surface of the cream.
-
5
Test by smoothing a bit of ganache or whipped cream on a plate — if it picks up residue, wash and repeat the drying.
Finishing touches
Make two or three spatulas in different sizes for fine and thick work. The inner aluminum layer also helps: it slides better over firm creams without sticking.
