My sister has been trying to make chile pepper vinegars and oils. She has run into a couple of problems with the oils and I now turn to you for advice. The first problem that she had was that after about a week, she checked the bottles and the oilwas seeping out of the stoppers. I told herto pour off some of the oil because of gases and expansion of the peppers. She did this Today she called to say that the peppers below the oil are fine, but that the part that has floated above the oil has molded. Any suggestions as to why and or what she should do.? I ad told her initially to make a slit in some of the peppers to make sure that the "heat" got into the oil and these sunk to the bottom and have stayed. Thanks in advance for your help Angel
