Recipe calls for a heaping teaspoon of a liquid ingredient I'm looking at a recipe for chickpeas (garbanzo beans) roasted in a spice mix, which looks yummy, but I'm confused by some items in the ingredients list.

I'm happy with this:


  1 heaping teaspoon curry powder


I simply take my 5ml measuring spoon, and get a heaped scoop of curry powder.

But for


  1 heaping teaspoon sesame, coconut or olive oil
  
  1 heaping teaspoon sriracha


I can see that sriracha might well hold its shape enough to form a heap. But what about the oil??
Obviously you can't "heap" a liquid.

What helps is if you remember that in cooking measurements are not set in stone. The amount given in a recipe can basically always be tweaked to your liking - a tablespoon need not be the "perfect" amount, but should be a good starting point. E.g. the siracha: some like their dish hotter, some less so.

In your case I'd interpret "heaping" as "generous" or "a bit more than". (The opposite of "scant", where you'd fill the spoon not quite full.) 

I'd start with a spoonful and add more to taste, if necessary.
