Only thing I can come up with is home made ice-cream. You can freeze the yokes in an ice tray so you can use them as needed. Once they are frozen, pop em into freezer bags.
Sorry I can't come up with anything else. Custards use egg yokes.
Your 14 egg yolks are surely long gone by now, but if you should have them again,
here are a few other ideas:
Quoting: MARIAN'S DAFFODIL CAKE (CHIFFON)
12 egg yolks (left over from angel food cake)
1 1/2 c. sugar
1/2 c. boiling water
1 1/2 c. sifted cake flour
2 tsp. baking powder
1/2 tsp. salt
1 tsp. vanilla
1 tsp. lemon flavor
Beat egg yolks until very thick and lemon colored. Add sugar in small amounts and keep beating. Add boiling water and beat 30 seconds, add sifted dry ingredients gradually, then add flavorings, beat all well (about 5 minutes). Bake in 350 degree oven for 1 hour in an ungreased 10" or 12" angel food pan. Cool upside down before removing. This is a great party cake, as you can serve it plain or with whipped cream, berries, or whatever.
Warm the eggs yolks and the sugar in a double boiler over a low heat, and then whip them with a wire whisk. Pour Marsala into the yolks, drop by drop, and keep beating.
The mixture will begin to foam and then swell into a light soft cream. Do not overcook or it will collapse.
Cinnamon and grated lemon rind may be added before pouring in the Marsala, and this liqueur in turn can be replaced with a high-quality white, sweet, dry or sparkling wine. Brandy or cherry brandy may also be added.
This is often served with fresh berries.
You can fold in whipped cream to make the Zabaglione more like a custard if you wish.
Quoting: Zabaglione with Fresh Berries
5 egg yolks
1/3 cup sugar
1/3 cup dry or sweet Marsala wine*
1 cup heavy cream (whipping cream), whipped until stiff
5 1/4 cups fresh berries (blackberries, blueberries, quartered strawberries, and/or raspberries)
* Marsala wine is traditionally used, but you can also substitute sherry, Madeira, Grand Marnier, sparkling or dessert wine. Can also combine wine with a spirit such as bourbon, rum, or Calvados, or other brandy, or add a favorite liqueur such as praline or Frangelico. Citrus juice and zest, vanilla, or ground ginger or other spices may be added along with the wine.
Set up a double boiler or a medium-size stainless-steel bowl over a pot of simmering water. Check to make sure the bottom of the bowl is not touching the water, or the eggs may scramble.
With a hand held electric mixer or thin wire whip, beat the egg yolks and sugar together approximately 3 minutes or until pale yellow. Slowly whisk in the Marsala wine and set the bowl over the simmering water.
Continue to beat, approximately 10 to 15 minutes, until the eggs triple in volume, thicken, and reach a temperature of 140 degrees F, as registered on an instant thermometer. The eggs will first become frothy, then as they cook, they will slightly stiffen but still hold the air. If you stop whipping or the water boils you might scramble the eggs. Be sure to move the beater or whip around the bowl so the eggs cook evenly. NOTE: If the eggs begin to curdle pull the insert away from the water for a few seconds to cool it (keep whisking).
Remove from heat and cool the mixture completely in the refrigerator. When the mixture is cool, fold in prepared whipped cream.
NOTE: Zabaglione can be made ahead and stored, covered, in the refrigerator for several days. Bring the sauce to room temperature before serving with your favorite berries..
In a serving dish (a large martini or wine glass makes a nice presentation), dollop some of the zabaglione. Add fresh berries. Finish by adding another good-side dollop of zabaglione and top with mint sprig and a few more berries.
Especially if made with the deeply coloured yolks of pastured chickens! I've had a number of folks tell me that they loved Zabaglione in Italy but it just doesn't taste as good when they try to make it here. When I suggested seeking out pastured eggs when they make this dish, a few of them did that and had some "Aha!" moments about the quality of ingredients.
