Yes all-over boil the size of green peas. So the bubbles cover the pan but they are not too vigorous. This is somewhat subjective so I recommend you watch the video. If you boil it too hard you may evaporate too much water and not have enough mixture to fill the molds, if you don’t boil it hard enough -you may have some left over. This is why we recommend only filling the molds 3/4 of the way first and then topping them up. If you consistently get less than 15 gummies add a little more water (one more teaspoon.) Remember: our recipe and dose calculator were developed to make 15 gummies, therefore 14 will be a slightly more concentrated batch.
