16 g of gelatine sheets (fish glue) or other of vegetable origin
Purple and yellow gel food coloring
PROCEDURE
Melt the butter in a small pan. Blend the biscuits or use a cloth, wrap them and crush them with a 'meat crusher' or a ladle.
Mix butter and biscuits.
Line a pan with baking paper. If you have it, use food-grade acetate strips for the edge (you will get a perfectly smooth edge).
Spread the mixture on the bottom and compact by leveling it with a spoon or your fingertips.
Place in the refrigerator.
Soak the gelatine sheets in cold water.
In a bowl, place the mascarpone, cheese and sugar and mix with an electric whisk (by hand if you prefer).
Melt the white chocolate in a bain-marie.
Heat half the cream and dissolve the well-squeezed gelatine sheets in it. Sieve to remove any undissolved gelatine pieces.
Add the white chocolate pieces and mix well to melt.
Add the chocolate mixture to the cheese mixture and stir.
Whip the other half of the cream and add it to the cream with a spatula and movements from the bottom upwards.
Insert the flower-shaped ring (if you have one) or a smaller cookie cutter into the center of the mold.
Divide the cream and color one part with your favorite color using a natural gel food coloring (for me purple). I remind you that there are foods that color a lot like mountain blueberries, raspberries, etc.
Fill a piping bag with the white cream and insert it into the outermost space (you can do this simply with a spoon or ladle with slow movements so as not to dirty the center of the mold).
Pour the colored cream into the flower ring (or pastry cutter). Use the back of a spoon to level the creams.
To obtain the flower effect you can use gel food coloring, purple and yellow, and a brush.
Place in the refrigerator for a few minutes. Remove the flower ring or pastry cutter before the cake solidifies. If you have waited too long, leave it at room temperature for a few minutes and you can carefully run a knife with a smooth blade around the shape before removing the ring.
Once the inner ring has been removed, place the cheesecake in the refrigerator to solidify until ready to eat.
