I have two large storage containers (one for unflavoured and one for vanilla), that previously held vegan protein powder and each hold a full bag of Huel.
I did have 3 when I used the Xmas flavoured Huel.
Every Sunday using digital scales, I put approx 50g of each into smaller plastic airtight containers (that hold about 150g), and keep these in a dry cupboard, and make up a whole week’s worth of these. Then every night I make up my Huel for the next day and stick it in the fridge. Repeat every Sunday…takes about 30 minutes or so of prep once a week, but works ok for me and I’ve been doing this for about a year. I have plenty of cupboard space in my kitchen so is no hassle.
I did find the bags a real pain to use, and the protein containers much more efficient.
I only use Vanilla and I empty a whole bag into a plastic dry food storer, the type of thing you use for cereal then keep it in the cupboard. I have also emptied 4 different flavour pouches into little screw on lid plastic containers from Asda. I then have 4 more of the small pots which I weigh 90g of Huel into each one along with one of the flavours giving me 4 pre-made Huels ready to take out or have at home.
Despite buying Huel for years now I have only just started refrigerating it so I might start making one up and leaving it in the fridge.
I empty a whole bag of Huel in the large container. 4 flavour pouches emptied into 4 small containers. The other two have 90g of Huel and 1/3rd of a teaspoon of one of the flavours inside which I’ll either make up at home or take out with me. Those small containers fit inside the Huel shaker.
