Try Nigella Lawson's clementine cake! It sounded really odd to me before I made it the first time -- blending entire clementines into a batter -- but the flavors are wonderful, and the cake is incredibly moist. (a good gluten-free option too!)

Food52 has several recipes that look promising (and some that could equally be horrible or awesome) http://www.food52.com/recipes/search?c=1&recipe_search=clementines.

I agree a sorbet or a cake would be a good use. But what about using the juice in a chicken glaze, or doing a ceviche with them (in conjunction with some lime juice, as i'm not sure if they have enough citric acid to accomplish the "cooking" of the fish. or the fish may have to just sit longer than it would with lime juice). then use the leftover rinds for some zest to make Clem/Cardamom spice cookies.

This recipe is amazing:

All you do is melt dark chocolate in a double boiler, dip pieces of clementine in halfway, put on a tray and sprinkle with sea salt. I made the recipe to use up some clementines that weren't too sweet, and it was perfect -- the combination of the tangy citrus, rich chocolate, and delicate sea salt, was just amazing.

The current Eating Well magazine has an awesome Clementine & 5 spice chicken recipe. I doubled the sauce to have some for my vegetables.

When I have an excess of clementines, I love juicing them for cocktails! Clementine juice with good gin and a splash of St. Germain is heavenly... so is a clementine margarita.

My mom uses whole (less the seeds) Clementines in this refrigerator muffin recipe (http://www.mennonitegirlscancook.ca/2008/10/refrigerator-bran-muffins.html) . She, and I quote, makes the muffins just like the recipe but with changes. I've also used the whole ground or grated fruit in quick bread recipes (think banana nut bread).

I made marmalade with mine before heading out of town for Christmas. It's really good in oatmeal. I'm thinking about trying to make a cocktail out of it sometime.

My wife and I can eat a pound of clementines as-is long before they go bad (it takes us about a week). If your husband bought them, make sure he's eating his fair share; hide a few in his work bag every day for snacks.

Smitten Kitchen made Nigella Lawson's clementine cake and posted a few adaptations/tips. I haven't tried it but I have never had a dud of a recipe from SK!

Juice them and make Clemintine Mimosas.

The chick that does "5 Ingredient Fix" has a stellar clementine cosmo recipe. I found it to be a little syrupy, so I reduced the amount of simple syrup and added a bit of club soda upon serving.

It is quite delicious.

I can't get enough Clementines in season, and buy them by the case, so in addition to all the uses above to stretch the season I candy them, make jam, and preserve them in honey:

It's best to eat it fresh for maximum nutrition and it won't take more than a week if you and hubby have one or two every day.. =D Or you can also..

- Toss in a salad with baby greens and nuts and dried cranberries and a little balsamic vinegar
- Substitute for water in baking to give a citrussy taste to cakes / scones / muffins / etc
- Make preserves or jam
- Juice it and freeze it, and make citrussy soda, tea, water, etc whenever you want

I love clementines, but find it frustrating that you can often only buy them in large quantities that go bad before I can eat them all! Here's a recipe fro a Sticky Clementine Quick Bread. http://therunawayspoon.com/blog/2010/02/sticky-clementine-quick-bread/

What? What about a salad?

Here's my favorite: Orange and Red Onion Salad with Honey Mustard Vinaigrette. Clementines are perfect for it! They are so easy to peel you don't need to section them.

They could also be replaced for mandarin oranges in just about any recipe. Like cold soba noodle salad. *nom*

Also, clementines dipped in hot fudge? Best dessert EVER.

I second Nigella Lawson's clementine cake.

Clementine pomegranate salsa! Halved and separated clementine segments, seeds of 1/2 pom (or more), cilantro, diced fresh jalapeno, lime juice, little bit of red onion. Yum!

I love to put clementines in a salad. My favorite recipe is with clementines, white beets, avocado and pinenuts. I call it the Crunchy/Smooth Sweet/Savory salad. You can get the recipe here: http://foodiegoeshealthy.com/?p=273.
Also, Food52 just had a citrus recipe contest. Home cooks just uploaded about 260 recipes there-- that should help you use up your bag in no time.
