Summers Here... Mediterranean-style salad recipe

Mediterranean-style salad (2 people)

1 bag of rocket
1 avocado cut into chunks
1 ball of mozzarella pulled into bite-sized pieces
Around a dozen or so olives
4 chopped vine tomatoes (or a mix of fresh and sundried tomatoes)
Cucumber – enough for a few slices/chunks each
1 pack / bundle of asparagus
2 tablespoons of pine nuts
Olive oil
Balsamic vinegar (optional)
Ciabbata bread (optional)

Grill/griddle or over roast the asparagus until lightly browned – you can add a little olive oil beforehand and it should only take 5 – 10 minutes. Meanwhile, throw the other ingredients together in a bowl and mix with a little olive oil and balsamic vinegar. Add the asparagus and some optional ciabbata bread, and you have a tasty, healthy Mediterranean -inspired salad!

Cholocate Easter Egg Vlog and Recipe


Watch Cornwall College chef lecturers Dave Trevena and Philip Oakes vlog on creating a fantastic chocolate Easter showpiece. We loved the chocolate Peter Rabbit and Easter Egg nest they made. Find out how to create a beautiful chocolate Easter Egg and a simple chocolate nest as a special Easter treat.

Easter Nest
Place a marble or granite slab in a freezer for 30 minutes whilst melting the high quality chocolate couverture (a chocolate that contains a high percentage of cocoa butter than baking or eating chocolate). Place the chilled slab on a large piece of paper to be able to work cleanly, then using a plastic or paper piping bag swiftly pipe loads of lines of melted chocolate from side to side on the chilled slab. The cool surface will shock the chocolate and set it so quickly it will not have time to form the chains of fat crystals we need for other purposes, so the chocolate strands remain flexible, can be picked up using a broad metal scraper then the bundle wound around to make the nest or even tied in a knot.

Easter Egg
To make an Easter egg, take two ½ polycarbonate or flexi plastic moulds and polish the inside surface well with clean cotton wool. The shinier the surface, the better the release and sheen on the chocolate.

Once polished, avoid putting your fingers inside the moulds as fingerprints will leave marks on the finished surface. On third fill the moulds with the melted and tempered chocolate, dark, milk or white, whatever your choice.

Tap the mould well with a wooden spoon to bring any trapped air to the surface. Now rotate and tilt the mould so that the melted chocolate completely covers the inside surface. Once the mould is covered inside, turn upside down and tap gently again over your melting bowl or over paper to drive any surplus chocolate out, to leave an good even coating inside the plastic shell. Now clean off any surplus with a plastic scraper, then press firmly down onto some plastic film or baking parchment to allow to set. Any surplus inside will gently run down to form a flange at the base, it will be trapped by the paper and will make it easier to stick the two halves together later.

Allow the chocolate to set to a ‘leather’ consistency, then again remove any surplus around the base with a plastic scraper, never metal, it could scratch the mould.

Now allow to fully set in a cool area. As the chocolate sets it will shrink by about 5%, and the appearance will change as air gets between the chocolate surface and the plastic surface, giving a silvery/shimmery appearance. Once set the egg halves will just drop out of the mould, sometimes a gentle tap will help. Refrigeration will accelerate the setting, but can cause condensation on the surface if left too long.

To assemble the egg, using plastic gloves to protect the shine, place both halves of the eggs onto a warm tray to just gently melt the flange then swiftly bring the melted edges together, so that they bond as the chocolate hardens again.

To decorate the eggs, make up a little royal icing, using 1 egg white and 150-200 gms icing sugar beaten well together to a firm piping consistency. The amount of icing sugar will vary according to the size of the egg, and you can use powdered egg white if concerned about raw egg content especially if giving the finished egg to very young children or other susceptible groups.

Colour half the royal icing a vibrant yellow, and half leaf green. Now pipe a zig zag of the green icing up across the egg like a fern frond. Before it sets pipe a zig zag of melted white chocolate over the green, then drag a cocktail stick swiftly through both from top to bottom to give the leaf effect. Use the yellow icing in a piping bag with a flower tube to pipe little yellow flower buds up the centre of the leaf shapes, and you now have a simple but bright, Spring like effect that will impress your friends and family.



Using and tempering chocolate

Temperature and Humidity 
Chocolate is best stored in a dry, cool, dark place: 13-15°C (55-60°F) is ideal. Do not store chocolate in a refrigerator and do not place chocolate next to anything with a strong smell – the chocolate will absorb the smell and be spoilt. Properly wrapped and stored chocolate will keep for up to a year.

Various types of ‘blooming’  effects can occur if chocolate is stored or served improperly. Fat bloom is caused by storage temperature fluctuating or exceeding 24 C while sugar bloom is caused by temperature below 15 C or excess humidity. To distinguish between different types of bloom, one can rub the surface of the chocolate lightly, and if the bloom disappears, it is fat bloom. One can get rid of bloom by re-tempering the chocolate or using it for anything that requires melting the chocolate.

The process of tempering chocolate always works best at normal room temperature, i.e. where the temperature is between 20-22°C (68-70°F) and the relative humidity below 50%. Check the conditions before you start and again while you work. The same room temperature should be used when moulding or dipping. Avoid draughts from open windows and doors when working and when allowing the chocolate to set. The chocolate should be allowed to set at room temperature, not in a refrigerator, as this can attract condensation and cause a dull surface.

Water and Chocolate
Never mix water with the chocolate if you wish to temper it. Even the slightest amount of moisture can cause the chocolate to seize. For this reason, make sure that the machine and utensils are thoroughly dry, that the chocolate is no more than 10°C colder than room temperature and that any pieces to be coated are free from surface moisture. If the chocolate is more than 10°C colder than room temperature, condensation will form on its surface as soon as it is exposed to the warmer conditions.

Tempering Chocolate
As the chocolate we buy is already tempered, if you are extremely careful and continually stir the chocolate over a gentle heat to 33°C, then you will have tempered chocolate ready to use. This is how chocolate tempering machines work. But if it gets slightly overheated  or there are hot spots the chocolate will not be correctly tempered, and you will have to follow one of the 2 ways below.

Generally, the chocolate is first heated to 43°C - 45°C to melt all the different crystals of cocoa butter. Next, the chocolate is cooled to about 27 °C, which will allow crystals to start forming. At this temperature, the chocolate is agitated to create many small crystal "seeds" which will serve as nuclei to create small crystals in the chocolate. The chocolate is then heated to about 31°C - 32°C.   After this point, any excessive heating of the chocolate will destroy the temper and this process will have to be repeated. The temper of chocolate can be measured with by allowing a small amount to set on a palette knife or silicone paper in a cool place. In 5 - 6 minutes it should be set, with a good surface sheen and quite a crisp snap.

Melting Chocolate
Melting chocolate can be done in a variety of ways. A double jacketed boiler or bain marie method can be used, but never over boiling water, 80°C is ideal. But be aware of getting water or steam in contact with the chocolate, this will make it impossible to use. A more common method is to use a plastic bowl and a microwave, stirring the chocolate after 30 seconds, and then every 10 seconds until melted. This method is also suitable for warming the chocolate from time to time as the working temperature should not drop below 30°C, but be aware that a powerful microwave could easily burn the chocolate so adjust the power settings.    Another way to keep the chocolate warm whilst using would be to use a hairdryer and gently blow heat over the surface of the chocolate whilst stirring.  Avoid having the bowl of chocolate on a cold surface, insulate the base using cloth or plastic or a wooden board.

Two classic ways of manually tempering chocolate are:
Working 2/3 of the molten chocolate on a heat-absorbing surface, such as a stone slab, until thickening indicates the presence of sufficient crystal "seeds"; the chocolate is then returned to the remainder of the molten chocolate and gently warmed to working temperature.  Stirring solid chopped tempered chocolate into molten chocolate to "inoculate" the liquid chocolate with crystals (this method uses the already formed crystals of the solid tempered chocolate to "seed" the molten chocolate). Ideally melt ¾ of the chocolate and use ¼ to seed the chocolate, adding a little at a time to get down to the lower temperature, then re heat gently to working temperature.
