It is understood that the ACTUAL making of מצה today is a very careful and meticulous process -and it would seem that there is a discrepancy in the process of people leaving Egypt by way of it simply not rising as they left with dough that didn't rise as it baked in the open air under the hot sun as opposed to in an oven as we bake it today. This opens up for several points:
- Is matzoh making today TRYING to replicate this process as described in the הגדה?
clearly the process of rolling, and baking needs to be done at high heat within 18 minutes and the SUN is not as hot as a מצה oven.
Either it is understood that we have a different method today in baking matzos, at least the Askenazi minhag (as opposed to timoni or sefardi methods)
Assuming there is a discrepancy between the הגדה and contemporary מצה making methods, either there is a reason the הגדה describes it this way which would seemingly be incorrect and there is a deeper meaning, OR perhaps we have added stringencies since the actual Exodus.
