Coffee, hot chocolate and cake at Second Shot in Marylebone

First impressions count, and the first impression we got of Second Shot‘s second branch north of Marylebone Station, was of a very friendly, local spot type of cafe. A small crowd were sitting around a table discussing a topic in an animated way. Various others were popping in or out, chatting with the barista, one person was sitting at a table with a laptop. And despite the fact that the weather was turning and the sky was becoming an ominous grey, the cafe itself seemed bright and open, with plenty of light coloured wood to complement the large windows.

We decided on a long black, hot chocolate and nut free brownie. Not wanting to spoil the initial taste of the coffee, I waited for the long black to arrive so that I could try that first before trying a bit of the brownie. The coffee was very well made, from Square Mile, and a perfect complement to the squidgy but moreish brownie.

On the walls, plants were hanging in pots with their leaves trailing down, while the light was reflected off a series of drawings sketched using coffee as an ink (they were for sale). It is surprisingly easy to make ink out of many different household (and not quite so household) items. Coffee is one base ingredient and, not surprisingly, makes a brown ink. But to bind the ink and to make it more viscous, gum arabic is frequently added to home-made ink recipes. The gum arabic is needed particularly if you are going to write with the ink with a fountain pen as it makes the ink viscous enough that it can flow through the nib.

Just as with the gum arabic, often ingredients are added to a product that are crucial to it, but that we do not realise they are there. Another example is the seaweed extract that is added to some plant based milks in order that they produce a better milk froth. But what if you don’t add all the ingredients at the same time, what happens if you add only one ingredient of the ink rather than all of those that are necessary?

One type of black ink that has been used for centuries is made from oak galls. It is even thought that ink based on galls was used to write the 4th century Codex Sinaiticus (the oldest complete copy of the Christian New Testament that we know of). The galls form on oak trees when the larvae of different types of wasp secrete a chemical that produces abnormal growth in the tree. The gall is the protective casing around the wasp larva, a type of home for the wasp larvae as they mature. Once the wasp has matured, it burrows through the growth which has turned from green to brown and it leaves a tiny little hole where it exited the gall. Galls can be seen on many oak trees during the summer and autumn and I’ve even seen them on the oak trees of various central London parks.

After the galls have been crushed and soaked, iron sulphate is added to the gall solution to produce a deep black ink*. Again, gum arabic is added to bind the ink to the paper and to increase its viscosity. But it is this ink that was also a popular ‘invisible ink’ first described over 2000 years ago. Philo of Byzantium** (who lived from 280-220 BCE) describes making an ink with the oak galls only. Forget about the iron sulphate for the moment. When it dries, the ink is nearly invisible on the paper, it can easily be missed and so can be sent to a collaborator as an invisible message. When the collaborator washes the paper with a solution of iron sulphate, the black ink appears on the paper and the message is revealed. Although the recipe has been known for two millennia, it has been used as an invisible ink even as recently as Mary, Queen of Scots and the American Revolution**.

This idea, of making the invisible visible, by adding a key ingredient seems to form a nice metaphor for the societal aspect of the work of Second Shot. On their website they describe this aspect as:

We’re changing perceptions on homelessness by being a destination that serves some of London’s best coffee, alongside a unique community atmosphere, amazing food, and just so happens to be changing lives.

We employ people who have been affected by homelessness, train them up and transition them on to long term employment elsewhere, helping them on their individual journey taking them from where they are, to where they deserve to be.

Key ingredients of training, and accompaniment on individual journeys that combine to change our perceptions but that are not realised by us as we consume great coffee at this friendly cafe: Making the invisible visible, but doing it without us even realising that we have received a hidden message.

Second Shot’s second branch is at 49 Church St. NW8 8ES
