Virginia et all: There's a great substitute for fresh Thai Chiles from Thailand. They are either green or red (we prefer the taste of the red) "Pickled Whole Red Chilli" put up in glass jars available at many Asian markets. Siam Worakit Food L.P., 200 grams at about $1.25 to $1.50. They are preserved in water, vinegar, sugar and salt and of course the sodium benzoate.1% They aren't as fiery as the fresh but have a great true Thai Chile flavor and I often use them in Thai cooking when I don't have the fresh. You need to double the quantity compared to fresh. Actually they are great as a snack straight from the jar. Mary-Anne
