The attempts by the Gemara and, in its wake, most of the classical commentators to explain our mishnah are at best unconvincing and leave too many holes that just cannot be plugged. However, salvation is nigh! Let us take a look at how the Tosefta presents the material in our mishnah. But, before we do that perhaps we should preface a short note about the Tosefta itself.
6:
It is customary to say with mendacious simplicity that Rabbi Yehudah the President of the Sanhedrin (Rabbi Yehudah ha-Nasi) wrote the Mishnah. Slightly less problematic would be a phrasing such as Rabbi Yehudah compiled the Mishnah. Some even claim that Rabbi (as he is affectionately known) edited the Mishnah. All such descriptions are misleading.
7:
The Mishnah is composed of individual mishnayot - the Talmud of Eretz-Israel more accurately calls them individual halakhot. We must bear in mind that until the time of Rabbi it was not acceptable to set the halakhot down in writing; they had to be passed on from teacher to student orally. (A sage was permitted to set down his own notes in what was called megillat setarim, a secret scroll, but this was for his own personal convenience: he was forbidden to use it in his teaching and it was supposed to be destroyed after his death. (However, there is evidence that some students did lay their hands on their former teacher's notes.)
8:
Thus it was that as each generation of sages passed the next generation inherited everything that their teachers had inherited together with all the new halakhot that had been created in the preceding generation. By the time of Rabbi (at the very beginning of the 3rd century CE) the mass of material was completely unwieldy. So, using the authority that he had as one of the great scholars of the age, and the authority he had as president of the Sanhedrin, and using the enormous clout that he had as being one of the richest people in the land, Rabbi made an eclectic selection from all the versions of each halakhah that had reached him. He then arranged them into a more or less coherent order, utilising a broad arrangement already promoted by Rabbi Akiva nearly a century earlier. This work is what we call the "Mishnah", and it was published some time before Rabbi's death which occurred in the year 217 CE.
9:
It should now be easier to understand the nature of the Tosefta. Actually, the Tosefta is just another collection of halakhot, just like the Mishnah is. However, whoever compiled it (and tradition says it was put together by a student-colleague of Rabbi Yehudah, Rabbi Ĥiyya) often selected a different version of a given halakhah to include in the work. Comparison of the two works, Mishnah and Tosefta, can help us understand the texts.

Having given this brief explanation of what the Tosefta is we can now set down here the text of the relevant halakhah as it appears in that work [Tosefta Avodah Zarah 1:3].
