Some of the classic French canapés involve vol-au-vents, which are puff pastry cups filled with tasty savoury or sweet fillings. These are surprisingly easy to make, especially with the availability of top-quality all-butter puff pastry in stores now.

To make the vol-au-vents, roll out a sheet of puff pastry to 3mm thick, or simply take out a pre-rolled sheet of puff which should be roughly that thickness. You will need 2 circle cookie cutters: one in the size that you want the base to be, and one the size that you want the hole to be.

One to two bites are best for canapés, but larger ones can be served as appetizers and entrees. Simply cut out twice the number of large disks that you want final vol-au-vents (plus a few extra for errors). Now use the smaller cutter to cut a hole in half of the pastry disks, forming O shapes. Next, egg wash the underside of the O shapes, and sandwich them onto the bases, creating cup shapes. Egg wash the whole item just prior to baking. Bake fully, cool and then fill with the pre-cooked filling.

When making a recipe that calls for whipped eggs (whites, yolks or whole), one thing to remember is that warm eggs whip to a greater volume than cold eggs.

You can leave the eggs at room temperature for a few hours, or you can place the eggs in a bowl and cover then with lukewarm water (about body temperature works well) for 30-60 minutes, but keep in mind, if eggs are heated above 60 degrees C they will cook.  Warm eggs are also easier to separate as the whites are more fluid when warm.

(Remember though, that when leaving eggs above 4 celcius, you may be allowing any salmonella bacteria in the egg to flourish.  The incidence of salmonella contamination in eggs in the US and Canada is somewhere between 1 in 20,000 and 1 in 100,000 however, so the risk is minimal -Chris )

Many recipes call for egg yolks to be mixed with sugar.  This mixture forms the basis of most custards, and desserts like sabayon/zabaglione.  The technique is pretty simple, but one major thing that can go wrong is what some people call ‘burning the yolks‘.  This happens when the yolks and the sugar remain in contact, without being whisked, for long enough that the sugar draws moisture out of the egg, which dried and hardens the yolk in spots.

This leaves what looks like grains of sugar that are darker than the rest of the yolk and cannot be melted or whisked out.  While fairly dire if it does happen, there are pretty easy ways to avoid this.

The first is to pre-weigh out the sugar, so that you can add it all in one go, and avoid prolonged contact between sugar and egg while you weigh out the sugar into the yolks.  The next is to whisk immediatly after adding the sugar, and not stopping until the mix is homogenous.  This mixture can how sit for a while, but whisk it around every now and then and again right before you use it.
