STEP ONE: Grab the most kick-ass apron you have just this moment, my favourite apron is this one my mum sent me which reads 'I love the Gong'.
STEP TWO: Melt the Copha, this weird and white substance takes a lot longer than butter to melt, I did the half block in the microwave for about 4 minutes, you can find it in the same section as the butter (it's vegetable shortening - FYI).
STEP THREE: Add the condensed milk into the melted Copha, a word of warning it looks a little squiggly and gross, plus considering you are looking at a stupid amount of fatty products combined I don't recommend reading the labels of these products (unless of course you have an allergy and don't want to end up in hospital) because you will just feel guilty.
STEP FOUR: Add all the other ingredients and stir well, then spread the mixture over the top of a layer of biscuits which have been placed upside down in a flexi-tray on baking paper.
STEP FIVE: This is not a part of Grandma's original recipe but I thought a passionfruit slice needed some passionfruit in it (Funny that hey...?) so I spooned the passionfruit pulp over the mixture and then placed the next layer of biscuits on top, facing up.
STEP SIX: Place in the fridge.
Grandma Beryl also writes that icing should be spread over the top of the slice but she hasn't written it down.... so I recommend the following icing if you're keen!
Add 1, 1/2 sifted icing sugar, 1-2 teaspoons of soft butter and 1-2 tablespoons of passionfruit pulp (minus the seeds). Stir.
TODAYS FUN FACT: Today is a public holiday here in Darwin and I've been dancing around to Backstreet Boys while making this slice - man they are great and I love rocking out my 1990's dance moves!
