PROBLEM: CONTEXT: Coat the outside of the cake with a moderate layer of icing to bind the stick cookies. This is analogous to the mortar behind facade bricks in building a wall.You could also put a drop of icing underneath the bottom, but that probably is not necessary.Update: I just noticed in the photo you can actually see some of the icing between the cookies, showing this is exactly how the show case cake in the photo was done. <sep> Q: How can I stick chocolate wafer sticks to a mudcake?

SOLUTION: Yes

PROBLEM: CONTEXT: In short, using port as a substitute for red wine will not wreck the dish.Though the flavour is different (and richer) and will make your bolognese taste different as a result, the taste should not be bad. I frequently do this as I am not a red wine drinker, and port keeps far better in an open bottle. I would recommend using slightly less than when using red wine, but this is highly subjective. <sep> Q: Will swapping the red wine in my spaghetti bolognese with port wreck the dish? A: using port as a substitute for red wine will not wreck the dish Q: Should I halve the quantity? A: I would recommend using slightly less than when using red wine <sep> FOLLOWUP_Q: Will it make it too sweet?

SOLUTION: Yes

PROBLEM: CONTEXT: Mast O Khiar, as you mention mainly consist of plain yogurt and cucumbers and most recipe do not require much more than that. Because of such, the shelf life for the yogurt product will be the shelf life of the yogurt itself. If it is a store bought yogurt, then the shelf life should be about 2 weeks in the refrigerator.Make sure to store the sauce in an air-tight container. Most tubberware should work. Those soup containers from Chinese takeout orders work perfectly.EDIT: After a bit of a debate in cooking chat, I decided to change my answer a little. The reason I said 2 week is because personally I had eaten 2 week old Mast O Khiar. However it could be recipe dependant so it could be different for a different recipe. However it is very easy to tell whether yogurt OR cucumber is bad.Mast O Khiar should have a very fresh/clean aroma. When yogurt turn bad, it releases a rancid smell. If it smells bad, dont eat it.If you see fuzzy mold it's a good idea to throw it out. <sep> Q: What is the shelf life of a yogurt product? A: the shelf life should be about 2 weeks in the refrigerator <sep> FOLLOWUP_Q: I made a large batch of cucumber yogurt sauce, will that stay good for 2 weeks too?

SOLUTION:
Yes
