A mirror glaze is judged by one test. Hold it at eye level and you should be able to read the reflection of the room in the top: not a shine, but a reflection with edges in it. It passes or fails in plain sight, with no way to tidy it up afterwards.
What a mirror glaze actually is
A mirror glaze is a set liquid, poured. It holds its gloss as it firms rather than drying matte the way an icing does, and it goes on in one pass over a dessert that has been frozen solid first. The freezing matters more than people expect: the cold surface brings the glaze to a stop almost on contact, which is what gives an even coat. Poured over something at room temperature, the same mixture slides off in sheets and takes the surface with it.
The reflection comes from the cake underneath
A glaze copies whatever it lands on. A dimple, a stray crumb or a thumbprint in the layer below will still be there at the end, magnified by the shine. That is why the finish belongs to mousse work: the seamless face comes from a mousse set against the inside of a mould and turned out, not from smoothing something by hand. The same principle is visible in our Black & White chocolate mousse cake and in the miniature version of it, where a flourless brownie base carries layers of double chocolate mousse, and in the Romeo & Juliet cheesecake. Surface first, finish second, in that order.
Temperature is the whole discipline
Too warm and a glaze runs thin, leaving a translucent film that shows every shade of the dessert beneath. Too cool and it thickens as it moves, setting in ridges that catch the light in stripes. The usable window is narrow, and reading the mixture is most of the skill. The pour itself is quick: one continuous movement, centre outwards, letting the excess fall away. A second pour over a half-set first one leaves a seam, which is why glazing has no second attempt built into it.
What we finish with instead
Our finishes are ganache and chocolate elements. There is no fondant here, no colourings and no bespoke decoration; customers choose from the designs already on the menu. Within that limit there is range. The Carolina choux pairs a dulce de leche mousse with a dark chocolate ganache montée, which is whipped ganache, light in the way a mousse is light, then finishes with roasted white chocolate and salted caramel. The Ferrari Rocher puts a shell of dark chocolate and roasted almonds over a flourless chocolate and hazelnut cake, so the snap arrives before the soft centre. The Snow White Chocolate Cake, one of the ten layer cakes, is covered in white chocolate petals made by hand. The edges of the pieces in our mini desserts cabinet are where technique shows.
Where to put your hands on the technique
Reading about a glaze and pouring one are different skills. Our cake decorating and baking classes run from $130 to $180 depending on the class: three decorating levels, a chocolate class covering tempering, and choux and tart classes; dates go up under upcoming classes. Public classes are capped at four, so you work beside Dhi rather than watching from the back of a room. He trained in French and Italian schools, has more than eighteen years behind him and uses no pre-mixes, so the reasoning behind each step gets explained as you go. That cap of four is also the practical reason to bring someone: book two seats and you have half the class, plus a second pair of hands to compare results with. If you would rather compete than concentrate, the Mini-Cake Decorating Challenge runs for four to twelve guests, up to ninety minutes, Tuesday to Friday between 11am and 4pm, listed with our other group activities. We have also written about what happens inside a decorating class, why we work from set designs, and the road that brought Dhi from Rio to Welles Street.
Ordering and visiting
Most things need two days' notice, and the checkout date picker only offers dates the kitchen can meet. The larger mousse desserts, the Black & White chocolate mousse and the Romeo & Juliet cheesecake, need three days. Cabinet items and drinks need none. Everything is collection only from our patisserie inside The Welder on Welles Street; we do not deliver. We are open 10am to 6pm Tuesday to Friday and 10am to 3pm Saturday, and the frequently asked questions page covers storage and transport.
