as the marshmallowist, I like to do things a little differently - I handcraft soufflé marshmallows from fruits, organic herbs and boutique alcohol.

Tea and chat with Adélaïde Aronio

I’ve collaborated with my friend, the artist Adelaide Aronio to create a limited edition series of one-of a kind boxes for our hot chocolate and toasting kits this Christmas. So, If you’re the sort of person that likes listening in on other people nattering in the pub then draw a bit closer because I recorded our chat just for you…

The Marshmallowist x Adélaïde Aronio

It was when I was living in Paris that I met my best friend Sixtine. She was completely Parisian in every way- from her swooshy slightly disheveled honey blonde hair; to her designer clothes to her 20 a day habit. We met whilst we were both worked for fancy European clothing brands in an equally fancy department store. We would take cigarette breaks together and swop discounts. She would take me on wild nights out and I completely adored how passionate and loud and intense she was. 

Bailey's Bonfire S'more Recipe

When Baileys asked me to collaborate on whipping them up a bonfire night recipe I was all in. November 5th is calling out for toasted marshmallows with a fire cracking flair. This isn’t just marshmallows for soaking up the last embers of the bonfire - this recipe is the Catherine wheel, the glitter flair and the rockets too. My most show-stopping S'more recipe to date.
