Escape Puzzle 759pc Witch's Kitchen

Based on popular escape rooms but in puzzle form! You stagger along, fall into a large hollow, and find yourself in a witch's woodland kitchen. Can you find an antidote and save yourself? Extra-challenging, because the boxtop image isn't the same as the puzzle picture, you have to decipher the clues on the in-box leaflet
 
The finished puzzle measures approx 70 x 50cm
