The downside to a new, unique recipe is that after you use that half-tablespoon of tamarind pulp/dark miso/black mustard seeds, the product sits stagnant in your cabinet, begging to be put to use.

The Washington Post has collected a few hard-to-use ingredients and provided recipes that use them. Have leftover cacao nibs? Mix them with nuts and cranberries for a jazzed-up trail mix, or substitute them in for chocolate chips in your next batch of brownies (and check them out sprinkled over lattes at right).

Kaffir lime leaves? Stuff them in your chicken as it roasts. Pomegranate molasses? Make it into a vinagrette, or drizzle it over ice cream.

If you still have questions, consult a site like Big Oven, whose Leftover Wizard tool allows you to choose three ingredients from the extensive drop-down menu and tells you if there's a recipe that incorporates them all.

Speaking of the cost effectiveness of kitchen gadgets, what do you think that your most and least used appliances/tools are? I know that I use my ice cream maker quite often, though it was voted as the least cost-effective appliance. On a near-daily basis, I use my espresso machine and my oven, and I use my toaster and blender less frequently. My stand mixer gets a good amount of use, too. I'm not going to work out the exact cost per use, but I think that these have all paid for themselves.

In terms of least used items, my waffle iron only makes occasional appearances in my kitchen, but I got such a good deal on it that it could be considered "cost effective" even if I only used it twice. My slow cooker is an appliance that I want to use more often than I actually do, as well. Fortunately, I don't think I have anything that I have never used. I'm sure that that is more indicative of the fact that I cook a lot than the potential usefulness of the gadget.

I'm willing to bet that sometimes the least used things in the kitchen are some of the least expensive, like my waffle iron. Things that were expensive tend to motivate people, myself included, to use them in an attempt to justify the cost. If it seemed like too good a deal to pass up at the time, you probably didn't buy it because you actually needed it, like that 6th unusually shaped whisk or yet another cheese grater that is now collecting dust at the back of the pantry.

How many times have you come across a neat looking gadget or seemingly useful appliance at the store and bought it, thinking that it would be useful? Maybe you rationalized your purchase by thinking , I always wanted to make my own ice cream, or perhaps even something like, the toaster on the TV show I watched last night looked just like this one and it made perfect toast! Not all kitchen gadgets are as costly, or as cost effective, as they sound. Pricegrabber.co.uk did a study of the cost-effectiveness of 30 household items, based on a survey of 1,500 UK shoppers that asked about how often they had used the items in the past year.

The least cost effective item was an ice cream maker, costing £19.48 ($35) per use! Clearly, nothing that is used only once or twice is a very cost effective item. Kitchen gadgets that were cost effective were tea kettles, averaging 5p (10¢) per use, and toasters, which ran about 18p (32¢).
