Mint Julep Cake (Round 2)

Remember the Mint Julep Cake? I thought it was delicious, but I still felt that it could be optimised a little bit.

Most importantly I was disappointed that the mint wasn't sufficiently prominent in the ganache. I realise this was my own fault for using mint syrup instead of mint extract. When I tried it a second time I used a LOT more mint syrup than I did the first time, but we still couldn't really taste the mint. That's when I started considering caving in and actually buying mint extract - but then I realised that the mint extract you can buy (at least around these parts) is always peppermint extract. Peppermint is banned in the Throat-Erator household.^[1] I realise I could try to make my own mint extract (and maybe one day I shall), but in the interest of having a quick procedure I decided to see what I could squeeze out of some fresh mint...

I bought 2 mint plants at the store, picked all the leaves and mashed them (I used my garlic press for this). The mass of mashed mint leaves didn't volunteer any juice, but when placed in a small fine sieve and pressed I was able to obtain about 1 tsp of a dark liquid with a rather peculiar smell. Now, I know that smell is highly concentration dependent, so the peculiar smell did not concern me - in fact, it encouraged me since I was aiming for a highly concentrated mint extract substitute. I went ahead and used it all - scroll to bottom for the result.

While I was at it, I also adjusted the amounts of both ganache and butter bourbon sauce.

Updated recipe as follows...

Ingredients (day 1):
- 340 g (12 oz) flour
- 400 g (14 oz) sugar
- 1 tsp salt
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1 tsp vanilla sugar
- 225 g (8 oz) margarine
- 2.5 dL (1 cup) A-fil^[2]
- 4 eggs
butter bourbon sauce (day 1):
- 100 g margarine
- 100 g powdered sugar
- 2 tbsp water
- 6 tbsp bourbon (I used Jack Daniels)
minty, white chocolate ganache (day 2):
- 265 g (²/₃ of a 14 oz can) sweetened condensed milk
- 200 g (7 oz) white chocolate
- juice squeezed from the fresh leaves of 2 mint plants

In a large bowl, flour was mixed with sugar, salt, baking powder, baking soda and vanilla sugar.

In a separate bowl, softened margarine was whisked together with A-fil and eggs.

The liquid was poured into the dry mix and everything was mixed until a smooth homogeneous batter resulted. The batter was poured into a greased and floured spring form of 22 cm (9 inch) diameter. The cake was baked at 175 C (350 F) for an hour (the difference in baking time since the previous edition is due to the fact that I moved in between - the oven in my new apartment is different).

While the cake was baking, the butter bourbon sauce was prepared: powdered sugar, water and margarine was stirred over medium heat till melted and homogeneous (shouldn't reach boiling). Then it was removed from the heat and stirred for an additional two minutes before the bourbon was stirred in.

While the cake was still hot holes were poked in the top (with a knife) and the butter bourbon sauce was poured over. Then the cake was allowed to stand and cool while absorbing the butter bourbon sauce.

Later, the cake was covered with film and stored in the fridge overnight before making and applying the ganache.

For the ganache I first squeezed the juice out of my mint leaves as described above. Then I melted white chocolate together with sweetened condensed milk over low heat with constant stirring. When homogeneous the heat was turned off and the mint juice was stirred into the mixture.

The ganache was allowed to cool for half an hour before applying it to the cake - after which the cake was immediately put in the fridge in order for the ganache to set (I did check up on it to make sure the ganache didn't flow too much - like the first time I made this cake).

I have to say I was very pleased with the result - the extra bourbon was spot on, as was the amount of ganache. But the best part was that this time we could taste mint!
