Combine the ground flax seed and the water. Whisk together in a small bowl and set aside to thicken.
In a medium bowl, toss the peeled, cored and cubed apples in the lemon juice to stop them browning. Set aside.
In a medium bowl, mix together the melted vegan butter, plant milk and thickened flax egg.
In a separate medium bowl mix together the sugar, flour, baking powder, spices and salt.
Add the better, milk, flax mixture to the dry ingredients and stir well to combine to form a thick batter. Using a slotted spoon, add the apples to the batter, leaving behind any extra lemon juice in the bowl. Mix the apples into the batter well and place in the fridge.
In a high-sided medium saucepan, add a few inches of oil and bring to around 175c. (I use a probe or candy thermometer to make sure the temperature is right).
Once hot, add a heaped dessert-spoon of the batter to the oil. Allow it to fry for around 30 seconds before carefully flipping it over and frying until golden brown all over. Use a slotted spoon or a spider to remove the fried fritter from the oil. Place on a wire cooling rack to drain while you cook the remaining batter.
Once all the batter is cooked, allow the fritters to cool fully for around 15 minutes.
In a medium bowl, whisk together all the glaze ingredients.
Once the fritters are cooled, drizzle a good dessert-spoon of the glaze over each fritter. Leave to set for a few minutes before serving.
