Macadamia madness

For my mum’s birthday cake, she put in an order for something with lemon curd. Lemon curd is also known as lemon butter. I had been wanting to experiment with macadamias in a cake for a while and thought a macadamia cake would compliment a tangy lemon butter beautifully.

Macadamias are a nut that are native to Australia and a few other countries in South East Asia. In Australia we are able to readily buy the nuts, either roasted and salted, raw or chocolate covered, and also buy macadamia nut oil, which is good for baking. I used both the raw macadamia nuts and macadamia oil in my cake. Because of the high oil content in the nuts, I processed them with the flour so that I did not end up with a macadamia nut butter type concoction.

This is my twist on recipes that use ground almond meal. I used 2 x 20cm or 8″ round cake tins to bake my cake. I used the lemon curd as a filling with cream for the middle and poured instead of icing over the top. My cake ended up looking quite rustic, because I was too impatient to let the lemon curd set fully and poured it over the cake while it was still quite runny.

To test if something is at “coats the back of a wooden spoon” stage,  take your wooden spoon you have been using to stir out of your liquid, and draw a line across the back of the spoon with your finger. If the line you have drawn stays there, and liquid isn’t bleeding down and distorting the line, it is ready.

    The birthday girl can happily testify that this cake was delicous. Not too sweet and a great texture, I extended the pleasure by using left over lemon curd on top of frozen limoncello yoghurt

  2. Yum! Looks amazing! A little unorthodox, but I love a birthday pavlova!

  3. I’m not that much of a online reader to be honest but your blogs really nice, keep it up!
    I’ll go ahead and bookmark your website to come back down the road. Cheers
