I don't know why but I suddenly got a hankering for a banana split but I'm going to make one instead of going to DQ.

 I bought Chapman's French Vanilla 2 liter box for $3.99 and the bananas for $1.69 (in this case 9 but it's 3lbs of bananas - obviously the size of the bananas determines the number you get).  I'm going to use 150ml of the ice cream and 1 banana.   I don't use a lot of fancy toppings, usually cocoa powder and strawberries but I'm splurging today with some homemade dulceata visine (sour cherry preserves) from a friend in Romania as well.  Sadly, I didn't have any pineapple to crush.

 ice cream - $0.29925
 banana    - $0.18778
-------------------------
 sub-total  ~ $0.49

Not too bad considering the historic price of a banana split.  Here's where it goes pear-shaped: Fresh strawberries are $8.99 for 2lbs and the cocoa powder (my wife only buys the organic stuff) was $27.95 for a pound.  I'm going to calculate in grams because it's easier on my brain - I cut up 50g of strawberries and sprinkled 7g of cocoa powder on the whole thing.

  7g of cocoa power - $0.4309 (almost the same cost as the base ingredients!)
50g of strawberries - $0.495 (more than the cost of the base ingredients)

 I put a couple of teaspoons of the sour cherry preserves - you don't need much as they pack a lot of flavour - but since I didn't buy it, I can't add the exact cost.   

 What banana split would be complete without the whipped cream?  I just buy the can and leave it in the fridge it was $5.49 for 400g - it says the serving size is 15g but who uses that piddly amount?  Let's say 40g (to make it really easy)

 40g of whipped cream - $0.549

 This banana split was quite large - it overfilled a cereal bowl and was probably enough for 2 (that didn't stop me from finishing it off though)

Ingredient	Cost
Ice Cream	$0.29925
Banana	$0.18778
Strawberries (50g)	$0.495
Cocoa Powder (7g)	$0.4309
Whipped Cream (40g)	$0.549
Total	$1.96183

 I was surprised to learn that the cost of each individual topping was worth nearly as much or more than the basic ingredients combined.  Those toppings are a luxury!  If bitcoin is going to dip much lower, I'm going to have to go with just the ice cream and bananas and forgo all the toppings. Ouch! I just checked BTC again... maybe I'll just have the bananas.
