... because they are 'environmentally unfriendly'?
Instead, I was strongly encouraged to buy silicone muffin cases, £5.95 for a set of four. Obv to fill one muffin tray, I'd need three sets. At a cost of £17.85. I seem to remember that 100 paper muffin cases used to cost £1.99 or thereabouts.
Is it just me, or is this slightly ?
